[ADSM-L] Linux HBA config for tape
2012-04-11 20:33:43
Hi All
TSM 6.3.0.0 server under RHEL 5.7. on an IBM xSeries, Qlogic HBAs
I'm running to 2xLTO5's in a TS3310 library and have 4Gb path to the
drives. The data compresses at about 1.5:1.
I'm seeing long-running backup stg tasks average 140MB/sec from disk to
tape or tape to tape. That is good, but it could be better. 140MB/sec
is LTO5 rated raw capacity so with this data I should be seeing 200 or a
bit more.
In a windows environment, you go into the Qlogic SanSurfer software and
tick a box that says this is a tape HBA and increases the block-size of
each transfer. How do you do this under Linux?
Regards
Steve.
