IBM Spectrum Archive EE and Quadstor

[Robert Adamczyk]

Hi, I've question if IBM Spectrum Archive Enterprise Edition is supported with Quadstor.

I've already configured both sites but i can't start Spectrum Archive cluster.
During startup:
# eeadm cluster start
2022-11-15 22:49:40 GLESL540I: Library name: TS3500, library serial: 0000074568310400, control node (ltfsee_md) IP address: 10.10.165.211.

2022-11-15 22:49:45 GLESL657E: Fail to start the IBM Spectrum Archive EE service (MMM) for library TS3500.
                  Use the "eeadm node list" command to see the error modules.
                  The monitor daemon will start the recovery sequence.

And in ltfs.log i see error result from command:
"Command /opt/ibm/ltfsle/bin/ltfs /ltfs -o changer_serial=0000074568310400 -o work_directory=/gpfs/fsA1/.ltfsee/meta -o admin_port=7600 -o umask=177 -o noallow_other returned exit code 1."

And when i try this command:
# /opt/ibm/ltfsle/bin/ltfs /ltfs -o changer_serial=0000074568310400 -o work_directory=/gpfs/fsA1/.ltfsee/meta -o admin_port=7600 -o umask=177 -o noallow_other

Enterprise Edition will not work. The software tries to fetch the
license of the tape library which only the physical library can
provide. The drive edition (standalone) opens the tape drive directly
and that will work, but will require manual mount/unmount of the
tapes.

Thank you for quick reply.

Does this solution works with Spectrum Protect (TSM)?

If so - are there any limitations ?

You should not have any problems with Spectrum Protect/TSM. Please set
RELABELSCRATCH to yes for the library. When a tape is expired it would
then erase the data on the virtual tape and will free up space.
