ssa performances

Helo:
We updated form AIX 4.3.3 to AIX 5.1-7 and after this we spent more than double time in read from external disks. Aparently the ssa cards microcode is at last level and all the ptf and apars are instaled.

Out backups expent more than double time, but curiously in read only, if we write in the external disk the performances are correct.

Please, Does anybody know somthing about this?

Thank you
Javier

RS6000 SSA Raid question

Hi Can I add disks on the fly to extend the capacity of an existing RAID 5 volume? It's created on a 4P Advanced SSA Raid Adapter. I need to extend a volume group, so I figured it would be easiest to extend the "physical disk" which is a RAID5 volume. Thanks. (1 Reply)
