Hello, We want to migrate our tsm 5.3.6 to new hardware with 5.5.3 installed. I have SCSI tape library 3573 on old server (5.3.6)which we use as copy pool only. We keep our primary pool on disks. I installed everything on new server and I physically moved tape library to new server. When I started restore I received error. I ran trace and I got:
15:05:51.313 [40][psntpop.c][1668][]:PvrPsTape GET_TAPE_DRIVE_INFORMATION, maxblocksize 65536 15:05:51.313 [40][pvrntp.c][1163][]:Opening NTP Volume FXK307L4 blocksize=0, Drive DRIVE2 (mt4.0.0.4) maxblocksize=65536. 15:05:51.313 [40][output.c][6385][]:ANR8939E The adapter for tape drive DRIVE2 (mt4.0.0.4) cannot handle the block size needed to use the volume So new server is using 64K blocksize. I also ran trace on exiting, old, production server with tape library connected. I just ran quick copy diskpool to copy pool. Trace: 15:52:24.734 [26][psntpop.c][1644]: PvrPsTape GET_TAPE_DRIVE_INFORMATION, maxblocksize 262144 15:52:24.734 [26][pvrntp.c][1146]: Opening NTP Volume FXK313L4 blocksize=0, Drive MT4.0.0.2 (mt4.0.0.2) maxblocksize=262144. 15:52:24.734 [26][pvrntp.c][1194]: Using the NoCopy method (True) with RS = 48 and BS = 262144, PVR's blockSize = 262144 Old server is using 256K blocksize to write to tape. I have case open with IBM TSM tech support. They said it is hardware (SCSI Adapter). I have IBM Adaptec 29320ALP (which is PCI-X card) on old server and same card 29320LPE (which is PCI-e express) on new server. I didn't call ibm hardware support because they are just dealing with replacing parts. I opened case with adaptec and ask them how to change blocksize; they said it should work if you didn't change registry settings. I don't understand why there is no clear answer how to change blocksize on scsi adapters. Any help appreciated. Regards, Joe Crnjanski Infinity Network Solutions Inc.
