Service Desk Call Handling Procedure
- RT tickets can be escalated by changing the Queue to backoffice with the Owner set to Nobody and the Status as new. Tell the requestor:
I am passing this request over to the experts who will be in contact when they have more questions or have some progress to report.
Delaying RT Tickets
- To delay a ticket for automatic re-activation on a given date set the Status to Stalled then use Dates to set a Due: date and [Save Changes].
New Research Students
Processing of postgraduate student admissions by administrative staff automatically generate an RT ticket with the following format:
Academic Year RS GivenName FamilyName crsid kit
for example:
#96184: 2015/10 RS Marcel ten Wolde mw245 kit
when they are added to the database.
The body of the message contains the name and crsid of the supervisor and the email address of the Research Student (RS). For example:
Supervisor: gt19 Email: mw245@cam.ac.uk
The following procedure applies ONLY to the above messages and NOT to other New Arrivals (where the New Arrivals procedure below should be used instead).
graduate admin
The auto-generation of these tickets relies on various heuristics which are sometimes wrong, and sometimes things change. The definitive source of all information relating to RSs (and RARSs) is graduate-admin@cl.cam.ac.uk. Information channels are not always clear, so if you get any information, please pass it on. If anything unexpected is revealed (a RS or supervisor says that a RS is not coming; someone says that the arrival date has been deffered; etc) forward the email graduate-admin@cl.cam.ac.uk pointing out the anomaly, and asking for confirmation that 'the system' is wrong and needs updating. Do not use an RT comment to do this, as graduate admin cannot 'reply' to an RT comment.
Phase 1
- Before doing anything with this ticket link it as a child of this years parent ticket:
#96194: AY2015 RS arrivals - please add new ones as stalled children and leave this ticket open - Note the student's name/CRSid and copy the child tickets's RT number
- Visit the arrival tracking database, add the RT ticket number to the PhD database by clicking on Select of the appropriate record then Edit the table that appears and insert the value as a number only, set Status to "supervisor" and click on Update.
- The next step is to return to the child RT ticket copy the supervisor's CRSid and use People then Type: Requestor and E-mail: CRSid and select CRSid@cl.cam.ac.uk and then Requestors: [tick] "Graham Titmus" <gt19@cl.cam.ac.uk> and [Save Changes] to make the supervisor as the sole requestor of the ticket.
- Then use Display and Reply to the initial email with the following message:
For the incoming student this request relates to, do you know if a new or existing group machine will be used, or whether one from the Lab Pool should be used please? Can the RS be given a free choice of Hardware [1] and Operation System [2], or do you as Supervisor want to recommend particular HW or OS, or even restrict the choice to a particular HW or OS? We will contact the student directly to decide what they want if you allow them to choose. [1] http://www.cl.cam.ac.uk/local/sys/platforms/equipment.html [2] http://www.cl.cam.ac.uk/local/sys/platforms/ Regards,
- Put the following comment into the RT ticket:
Go to Phase 2 of the New Research Students procedure at https://wiki.cam.ac.uk/cl-sys-admin/Service_Desk_Knowledgebase:_Resources#Phase_2 when the Supervisor replies with the requested information.
- Then set the RT ticket owner as nobody with the status as stalled with a Date Due of one week hence.
Phase 2
- If the Supervisor replies that the student is not coming, pass the info on to graduate-admin@cl.cam.ac.uk by email (not RT) , mark the ticket as Rejected, move it from being a Children: to being Referred to by:, and in the arrival tracking database set Status to withdrawn or deferred, and set the Notes field accordingly.
- Otherwise. when the Supervisor replies with the requested information:
- Copy the student's email address from the initiating email
- Click People to set the following:
- Type: Requestor and E-mail: student's email address for the student
- Type: Cc and E-mail: CRSid and select CRSid@cl.cam.ac.uk for the supervisor
- Requestors: [tick] <CRSid@cl.cam.ac.uk> to remove the supervisor as the requestor
- [Save Changes] to make the student the Requestor and the Supervisor the Cc
- Display the RT ticket
- If the Research Student has a CRSid, check if the student is already in the Inventory database is an assigned user of a machine (i.e. is already at the CL). If so note the details and add the machine's name to the RT Ticket's subject.
- Update the arrival tracking database
- update Status. If the supervisor has specified the system to use, select the appropriate value, such as Install OS, Install HW or completed. Otherwise, set it to student
- update the Notes field. If the supervisor has stipulated a preferred or mandatory provision then briefly summarise the info, along with any information from the Inventory database. For example:
CRSID mw245 USN 301711634 RT 96184 OS Std Linux Hardware std PC and LCD Machine 19138 Status completed Notes keep existing machine
- Using Reply email the incoming Research Student with the following message (editing as required):
According to the database, we are expecting you to come to the University of Cambridge Computer Laboratory to start a PhD in October 2015. Welcome! Are you still planning to come then? If so then please note that you should not expect any resources to be available ahead of the induction date which will be notified to you by Graduate Admin (Monday October 5th). If you are coming, you'll be allocated a pool machine as described in http://www.cl.cam.ac.uk/local/sys/platforms/equipment.html http://www.cl.cam.ac.uk/local/sys/platforms/ has information about the choice of operating system.
If they already have an assigned machine add:
I note you are already using machine "<<machine name>>", would you like to continue to use that and if so do you want the OS refreshed to the latest version, leaving scratch space as it is?
If the supervisor has specified or suggested an operating system add the following (with the appropriate OS and machine type set):
Your supervisor has suggested you start with Ubuntu 14.04 LTS on a standard Computer Lab PC Please let us know if you don't think that is suitable.
If the supervisor has not specified anything then add:
Please let us know what equipment and OS you would prefer.
- Put the following comment into the RT ticket:
Go to Phase 3 of the New Research Students procedure at https://wiki.cam.ac.uk/cl-sys-admin/Service_Desk_Knowledgebase:_Resources#Phase_3 when the Research Student replies with the requested information.
- Then set the RT ticket owner as nobody with the status as stalled with a Date Due of one week hence. If the due date is reached and the ticket reverts to open, email the Research student again as above, and stall the ticket again with the date another week hence.
Phase 3
- If the Supervisor replies that the student is not coming: pass the info on to graduate-admin@cl.cam.ac.uk by email (not RT) , mark the ticket as Rejected, move it from being a Children: to being Referred to by:, and update the arrival tracking database to have Status of withdrawn or deferred and summarise it briefly in Notes.
- If the Research Student says that they are not coming: thank them, email their supervisor, pass the info on to graduate-admin@cl.cam.ac.uk by email (not RT) , mark the ticket as Rejected, move it from being a Children: to being Referred to by:, and update the arrival tracking database to have Status of withdrawn or deferred and summarise it briefly in Notes.
- If the Research Student replies with "I have not yet received a formal offer":
- pass the info on to graduate-admin@cl.cam.ac.uk by email (not RT)
- Stall ticket until the RS receives an offer, graduate admin convinces the RS that (s)he does have an offer, or the offer is declined (as advised by Graduate Admin)
- Update the arrival tracking database Notes field with a *brief* summary of the info useful at *this* stage of the process with something like:
"Has not received formal offer. graduate-admin asked to clarify" - Issues could be:
- formal letter was sent, but didn't arrive
- formal letter should have been sent, but by mistake was not
- the automated WorkFlow has triggered a user to be put into the system too early (gt10 needs to fix)
- When the Research Student replies with their requirements:
- Add the options they have chosen to the PhD arrival tracking database - Select' and then use Edit at the bottom of the list, e.g.
OS: Linux
Hardware: Std PC and LCD
Status: install OS
and set the status to be Allocate - The RT ticket then needs to be passed on to oper queue to provision with status set to stalled.
- Thank them for the information using a message such as:
- Add the options they have chosen to the PhD arrival tracking database - Select' and then use Edit at the bottom of the list, e.g.
Thank you for letting us know about your requirements. If we need any further details we will contact you shortly. In the meantime you may care to familiarise yourself with the IT ethos of the department by reading http://www.wiki.cl.cam.ac.uk/rowiki/SysInfo/BedtimeReading and the pages to which it points.
New arrivals
Processing of new arrivals by administrative staff automatically generate an RT ticket with the following format:
CRSid has a HR Role starting ??/??/2015 requiring equipment v#VisitorID visitor name
when they are added to the database.
- Copy the RT ticket number (without the #)
- Click on the URL in ticket like: https://dbwebserver.ad.cl.cam.ac.uk/Administration/Visitors/VisitorDetails.aspx?ID=999
- Enter your CRSid & Computer Lab password if requested
- Click the [Edit] button at the bottom left of the form
- Paste in the RT_Ticket & click [Update]
- Desks & Rooms: Allocation of desks/rooms is done by Reception - we don't care about them until we actually need to install equipment. Reception see a parallel workflow and use the OpenRoomMap (ORM). If there seems to be a problem, contact them, and ask them which desk/room to use (but remember that they cannot reply to an email sent to them using an RT comment!) Once the 'OpenRoomMap (ORM) is updated use it to see where the user 'will be'. If room information is available [Edit] Allocated_Office & [Update].
- Copy notes for any specific instructions to paste into the RT ticket
- Return to RT
- Click Comment and paste specific equipment requests into the RT ticket
- What happens next depends on what's been requested and who has the equipment:
- If there are no specific equipment requests Reply to the RT ticket requestor asking:
What do you intend to provide for the person please?
In RT set the Owner as Nobody & Status as Stalled (with a suitable Due date) & leave the Queue as Sys-Admin and then [Edit] the inventory database Equipment_state with Asking and [Update] - If a computer has been requested or allocated to the person but is already allocated to someone else who is still here, Reply to the RT ticket requestor asking if the new person should be made the "assigned user" of the computer (i.e. User in the inventory, the person who has 'cl-asuser' and 'sudo' privileges to do things such as install software on a managed Linux PC, & have access to the machines BMC if it has one). In RT set the Owner as Nobody & Status as Stalled (with a suitable Due date) & leave the Queue as Sys-Admin.
- If a non-specific machine (e.g. Linux machine) is requested for an RA, reply and ask the PI whether they already have a machine, or whether they want to buy one. If they say that their grant explicitly forbids buying WSs, then they are allocated a charity case or grace and favour machine - see Special information for re-use of PCCL0xx machines for 2015/10 for more on this for the academic year 2015/16.
- If a computer has been requested or allocated to the person and is not allocated to anyone or their end date has passed then the new person should be made the "assigned user" (i.e. User in the inventory, the person who has 'cl-asuser' and 'sudo' privileges to do things such as install software on a managed Linux PC, & have access to the machines BMC if it has one).
- If access to servers is required Reply and CC the Sponsor/Personresponsible for each server as they need to formally agree to that access in order to meet the Cam AUP (even though almost all machines are accessible by anyone in the Computer Lab by default). In RT set the Owner as Nobody & Status as Stalled (with a suitable Due date) & leave the Queue as Sys-Admin.
- If there are no specific equipment requests Reply to the RT ticket requestor asking:
- Finally when all the required information has been gather escalate the RT ticket by leaving on the backoffice queue with Status as new and Owner as Nobody. [NOTE: The Equipment_state field requires OK Inventory No.???? MachineName to complete it and stop it being picked up as a "Outstanding equipment requests for arriving visitors/staff".]
Creating accounts for people arriving
See Account creation request for <CRSid> arriving <date>" or Outstanding equipment requests for arriving visitors/staff
Requests for machine moves
The move process involves:
- Reception allocate people to a free desk in a room using OpenRoomMap (ORM).
- When people are physically moved into a room, whoever moves them (e.g. the operators) checks that the OpenRoomMap (ORM) information is correct, reporting any erros to Reception, then moves them and when the move is complete updates the Staff List.
- Users can update their details within a room (e.g. if they move tables etc).
Requests for machine moves are raised by Reception after they allocate a new office.
- Take the RT ticket and check the equipment the person has in the equipment Inventory.
- Check what phone may need moving in the VOIPList.
- If there is some equipment to move then list it and pass the ticket over to the operators.
- Set the Queue to oper, the Owner to Nobody and with Status as new.
After the operators have moved the machine they should provide back details of which port the machine is now plugged into on the ticket.
1. Take the RT ticket and then update the inventory with the new machine's location.
2. Check that the information in the Staff List and the OpenRoomMap (ORM) is correct.
3. Using Updating VLANs in the Cisco switches note the VLAN of the old switch port and then set the old switch port where the machine was to no longer be on the VLAN it was with no switch port access vlan vlan# then set the new switch port to access the VLAN that was removed.
4. Check you can access the machine remotely
5. To check the "assigned user" on Linux desktop machines: On svr-ssh-1 or sandy run ssh -K $host ls -l /etc/user-config/bundles
-rw-rw-r-- 1 qg216 sysadmin 3565 Nov 3 20:06 /etc/user-config/bundles
to check the user can install software as the "assigned user" (i.e. sysadmin). If not see Adding privileged or 'assigned' users
6. To check the "assigned user" access to BMC on Linux desktop machines: On svr-ssh-1 or sandy run cl-amttool $host user list
kikyo-bmc Registered 3 AMT user accounts: $$uns 1 realm LocalAccessPermission Enabled <system account> $$OsAdmin 6 realms LocalAccessPermission Enabled <system account> qg216 21 realms AnyAccessPermission Enabled
to check that the user has AnyAccessPermission Enabled. If not see (4.7) BMC ACL - when up if present.
Leaving Procedure
Normally a leaver is only noticed by us after (1) has been completed but...
1) Tell Reception that he has left - they update the staff list to say he's no longer Valid.
2) use the DB to find what equipment he has.
2a) Anything which is 'Lab pool' (typicallu owneed by 'RTSG', pb22, gt19, 'Lab', 'PWF' or other pseudo users) should be returned to GC20 - ask oper to do that - phone to GC12.
2b) If there is anything owned by the Host / Supervisor / PI, contact them and ask what should be done, e.g. donated to the Lab Pool, or re-deployed elsewhere.
User Can't install Software under Linux
See Adding privileged or 'assigned' users
Machine Hardware Problems
Graham Titmus (22 Apr '15)
Machines with noise issues etc.:
Change the RT ticket queue to hw-admin with status New AND email a comment Nick Baterham (nb@cl.cam.ac.uk) to alert him.
Operating System Upgrades
- See http://www.wiki.cl.cam.ac.uk/clwiki/SysInfo/HelpDesk/Resources - Arrivals/Upgrades/Replacement/Disk
and
Dual boot requests
Piete Brooks (06 May '15)
Dual booting is discouraged in favour of running virtual machines instead. The options are either Computer Lab Windows + virtual Linux, or Computer Lab Linux + virtual Windows See http://www.cl.cam.ac.uk/local/sys/platforms/#dualboot
Reclaiming Equipment after someone leaves
1) Ask the visitor's sponsor if the visitor has left and if it's OK to reclaim the equipment
2) Once the sponsor has replied in the affirmative, add 'Reclaim' to the subject line and move the ticket to the Oper queue

Finding out a machine's operating system
Graham Titmus (26/05/15)
Whilst it's only the best guess you can try logging into laira and running the command:
cl-hosts -p MachineName
to find out what operating system a machine is believed to have.
