Replace a tape drive in HPSS
A call at Oracle should be generated automatically for T10KD drives.
Otherwise open a service request at Oracle https://support.oracle.com with the Tray Serial Number.
The Tray Serial Number of the drive can be determined via SL-Console or in file
https://team.kit.edu/sites/scc-sdm/Dokumente/Data_Protection/Hardware/HardwareListDataProtection.xlsx?Web=1
When the call at Oracle was opened, please set the Icinga State for the Check "Drive_Trap" of the corresponding library to OK: https://icinga.scc.kit.edu/icinga-web
1. preparation of replacement 1.1 log-in hpss core and hpss gui log in on active hpss core (e.g. hpsscr01 or hpsscr02) /opt/hpss/bin/hpssgui.pl & 1.2 set drive "locked" HPSS GUI: select Monitor: Device/Drive List (if necessary choose Preferences "Movers(tape)") select the drive to be replaced set "locked" the drive to be replaced: Drive Administration-->Lock after dismount also "lock" the device: Device Administration-->Lock 1.3 drive is ready for replacement
2. replace the drive in the tape library 2.1 Physical exchange Physical exchange of the drive is done by oracle engineer. If neccessary, set the IP adress, documented in https://team.kit.edu/sites/scc-sdm/Dokumente/Data_Protection/Hardware/HardwareListDataProtection.xlsx?Web=1 2.2 documentation of exchange insert documentation of the replacement in LSDF Wiki (System Logs): http://wiki.scc.kit.edu/lsdf/index.php/hidden:System_Logs_(HPSS,_TSM)
3. Reconfigure and reactivate the replaced drive 3.1 Show the drive configuration in hpss gui HPSS GUI: Select the drive Choose Configure Read field "Drive Address" x,y,z,t 3.2 Reconfigure the replaced drive in acsls log-in on acsls mashine (scc-stk-lib01, 172.21.238.64) su - acsss check configuration of replaced drive in acsls (has still old serial number) cmd_proc -ql ACSSA> display drive * -f serial_num ACSSA>logoff reconfigure the replaced drive in acsls (automatically sets new serial number) config drive x,y,z Drive id Old Type New Type chg Drive Serial Number -------- -------- -------- ----------------------- 0 T1D unchanged * 579004007294 NOTICE: "drive id" is the number t read from Step 3.1 3.3 Add the replaced drive to StorSentry configuration Verify, that StorSentry Server sees the new drive via commands sg_map and sg_inq for example: [root@scc-histor-n01 ~]# sg_map -st -x -i | grep T10000 | cut -f 1 -d " " | while read drive; do echo $drive;sg_inq $drive | grep 57900400xNEW; done ... /dev/sg95 Unit serial number: 57900400xNEW Note: In this case device /dev/sg95 is used for the new drive. Afterwards do an update to the configuration: [root@scc-histor-n01 ~]# /opt/histor/storsentry/agent/support/Update_config.sh -force -auto Start the GUI and verify the exchange, the new drive will be seen by its serial number.
If the new drive is not seen by its serial number, a reboot of the StorSentry Server might help to add the new drive to the scsi layer. Rename the drive via the GUI: Administration: Log in (no password) Rename the old drive from DriveName to DriveName-removed. Rename the new drive from "SerialNumber new drive" to DriveName. Via Administration/Libraries the drive can be put in the right logical ACSLS library. 3.4. reconfigure the drive in hpss HPSS GUI: Devices and Drives-->select the drive Read field "Mover" "that is the mover the drive is connected to" log-in on the mover ls -l /dev/hpss --> note the new SerialNumber HPSS GUI: change field configure-->Device Name with the new device read from mover Press Update at the bottom of the window 3.5. unlock the drive in hpss HPSS GUI: Devices and Drives-->select the drive Drive Administration-->Unlock 3.6 check documentation of drive exchange in LSDF Wiki (System Logs) Check if exchange was documented: http://wiki.scc.kit.edu/lsdf/index.php/hidden:System_Logs_(HPSS,_TSM)
