Cancel all processes
Hi Is there a possibility to cancel all active processes at once, like "cancel session all" for sessions? I need such a command for an installation routine. Regards Patrick
Antwort: mixing LTO1 and LTO2 tapes in a 3584 with only LTO2 drives!
Hi We have tested LTO1 tapes in a HP MSL5030 with two LTO2 Drives. But we have always copied the data stored on the tapes to a disk pool. Then we relabeld the LTO1 tapes in the LTO2 drives and wrote the data back onto the tapes. We have never tested to read the data of LTO1 tapes written by LTO1 drives with LTO2 drives. I don't know if it is possible for you to do so. Best regards Patrick Rainer Bill Boyer <[EMAIL PROTECTED]> Gesendet von: "ADSM: Dist Stor Manager" <[EMAIL PROTECTED]> 01.04.2004 20:11 Bitte antworten zu "ADSM: Dist Stor Manager" <[EMAIL PROTECTED]> An [EMAIL PROTECTED] Kopie Thema mixing LTO1 and LTO2 tapes in a 3584 with only LTO2 drives! I have a client with a 3584 library filled with LTO1 tapes and 4-LTO1 HVD drives. They want to swap all drives out for fibre attached LTO2 drives. Reading on www.lto.org, I see that LTO2 is supposed to be able to read AND write to LTO1 media in LTO1 format. If this is really the case, then the installation of the new drives and conversion to a totally LTO2 tape could be minimal. Anyone mixing tapes in an all LTO2 library?

Antwort: Restore Volume Problems
If there is no copy of the volumedata stored on a copy storage pool, you cannot restore the volume because there is no alternative data source. Check the difference between your primary storage pool and your copy storage pool. Every time i have such a problem, I set the tape to unavailable and wait till the tape gets less utilized. Then i check the importance of the data left on the tape. If there are no important files left, I simply delete the tape (with "discarddata=yes"). If there are any other solutions, I also would appreciate to hear them!

I did the typical procedure in the Tivoli Admin Manual to restore the volume. All the tapes specified in the restore vol x prev=yes where brought on site. However after we did the restore I got a warning "ANR1256W" regarding some files couldn't be restored. Doing a restore vol x prev=yes doesn't show any volumes that are needed to restore it. Reclamation has not occured since the tape was destroyed. The tape is beyond repair and can't do a move data from it. Has anyone run across this? Any recommendations? TIA Dave
Antwort: Re: Antwort: Re: 2 LTO-Drives Load-Balancing
ffer about 20MB/s. The question: Is the transferrate of the diskdrives split up for the tape drives to 50% for each drive? (10MB/s per drive) (Also means 50% per process) Or uses one drive the full transferrate which is possible for one drive (15MB/s) and the other drive only gets the rest (5MB/s)? My problem -> 5MB/s means permanent Stop-and-Go-mode for one drive. I would like to hear, that the TSM-server splits up the transferrate. This means each migration process/job uses 10MB/s. Thank you.

LTO2 drives using LTO1 tapes
Hi Is there anyone using LTO2 drives with LTO1 tapes? How does the transferrate changes? What i know is: LTO2 drives with LTO2 tapes provides 30MB/s maximum and 15MB/s minimum. LTO1 drives with LTO1 tapes provides 15MB/s maximum and 8MB/s minimum. but how does LTO2 drives with LTO1 tapes work?? I have heard that the maximum speed for this case also would be 15MB/s. But what is the difference? Is the rotation of the drive slower? Does anyone know, if there are compatability problems combining those two technologies? Sorry for this non-TSM-question, but there is no LTO forum and experiences with such combinations are very rare. I am thankful for every answer. Best regards Patrick

Hello again Sorry. Maybe my question can be wrong interpreted. For example: I have two migration processes from disk stgpool to tape drive. My diskdrives offer about 20MB/s. The question: Is the transferrate of the diskdrives split up for the tape drives to 50% for each drive? (10MB/s per drive) (Also means 50% per process) Or uses one drive the full transferrate which is possible for one drive (15MB/s) and the other drive only gets the rest (5MB/s)?
