TSM server recovery with database copy2 volumes

[mfarooqi]

Hi,

I have a TSM/AIX server. TSM server database copy1 volumes are on filesystem A. TSM server database copy2 volumes are on filesystem B. If I loose filesystemA, can I restart TSM server with copy2 volumes? If yes what do I need to do?

Thanks,

Hi, there's nothing to do to start the server with only one copy. The second will be offline.But then you should try to get your second copy online and sync'd as soon as possible.

Hi, thank you for the reply. Let me rephrase the question. TSM server is down. AIX system is rebooted. I only see filesystemB which has TSM database copy2 files. Should I be able to restart TSM server?

Hi,

so you have your DB copies on fsB which is online and TSM server code on the working filesystem.

When you start TSM, it searches dsmserv.dsk file where location of DB and RLog files are kept and tries to put them online. If the primary DB volume is cannot be varied online, TSM prints out a warning message and switches to copy volume ...

So if you have DBcopy AND RLog copy on the working filesystemB you should be able to start the TSM.

Can you provide us with error messages you get?



Hope it helps

Harry

Hi,



I have TSM db copy1 on /tsmdb1 and /tsmdb2. I have TSM log copy1 on /tsmlog1. I have TSM db copy2 on /tsmdb3 and /tsmdb4. I have TSM log copy2 on /tsmlog2. Both db and log copy1 and copy2 files are listed in dsmserv.dsk file. I have set MirrorRead db and log to Verify.



I bring down TSM server, unmount /tsmlog1, /tsmdb1 and /tsmdb2 filesystems. When I try to bring up TSM server it complains that it cannot find copy1 db and log files and aborts with 'ANR0259E Unable to read complete restart/checkpoint information from any database or recovery log volume.' Here is the console output:

Hi,

I cannot see any obvious error for now .. can you provide us with

"q dbvol f=d" and "q logvol f=d" commands?

Can you read the db and log volumes on /tsmdb3(4) and /tsmlog2 ?
