hidden:Replace a tape drive in HPSS

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 on hpss core

1.2 call hpss gui 
/opt/hpss/bin/hpssgui.pl &

1.3 set drive "locked"
select Monitor: Device/Drive List (if necessary choose Preferences "Movers(tape)")
select the drive to be replaced
set "locked" the drive to be replaced: Device Administration-->Lock and Drive Administration-->Lock

1.4 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

2.1 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:
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
cmd_proc -ql
ACSSA> display drive * -f serial_num
ACSSA>logoff
 
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
f.e.:
[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

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

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.

8.4. reconfigure the drive in hpss

log-in 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 shown on previous step 
ls -l /dev/hpss --> note the new SerialNumber

change field configure-->Device Name with the new device read from mover 
Press Update at the bottom of the window

8.5. unlock the drive in hpss

Devices and Drives-->select the drive
Device Administration-->Unlock
Drive Administration-->Unlock

8.6 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)

8.7 Update Device Name on the StorSentry GUI

Reboot Storsentry, if neccessary, to add the new drive into the scsi layer
Afterwards do an update to the configuration if the drive is not seen

[root@storsentry-test ~]# /opt/histor/storsentry/agent/support/Update_config.sh

Start the GUI and verify the exchange, the new drive will be seen by its serial number.

StorSentry GUI:
Administration: Log in (no password)
Rename the replaced drive from DriveName to DriveName-removed.
Rename the new drive from "SerialNumber of the new drive" to DriveName.
