thanks for your response.......we have been running our tsm server for a year with maximumsglist at the default value.... if what your saying is true about restore capability that would explain a few things.. we have done major restores and not got all the data back we expected. Is there an IBM document on all this somewhere other than IBM flash 10135?
Another question, our tsm server has multiple qlogic hba's. I believe the maximumsglist will take affect on all the adapters. However some of those adapters are used just for SAN disk connectivity. Will changing this parameter have any impact on disk access/performance?
Thanks again
Chris

You must set this option higher than 0x41 (I prefer 0xFF) on *any* machine accessing tape over SAN - be it TSM server, TSM Storage Agent, or any other product. Afterwards you must perform the backup *again* - some times with low maximumsglist setting the data is reported to be written but is not completely. Thus your backup might be not restoreable.

Hi
Well the quest for lan free backups continues....
I got past my initial problems by upgrading storage agent to 5.1.5.4 (same level as server)
Yesterday I managed to run an image backup lan free, 150Gb in 1hr 15 minutes so was quite happy with that. However when I went to restore it 5 minutes later it failed and the server actlog gave me
10/29/2003 16:39:39 ANR8939E The adapter for tape drive DRIVE2WWPK (mt1.0.0.5) cannot handle the block size needed to use the volume.
I then tried another image backup and it failed with the same error. During the time of the image backup working then stopping working nothing had changed.
I believe the above error is to do with the registry entry for maximumsglist. On the storage agent client I have had maximumsglist set to FF for a while.
My question is do I need to set the same registry key on the TSM Server itself? If not then what else can be causing this
TIA
