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 (check if 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 field Device Name has not to be changed anymore, since it contains Drive Node WWN which does not change select Information: Drive Info at the right, change SN in field comment 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 Device 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)
