[Veritas-bu] Slow catalog backup
2007-06-01 07:48:25
Hi All
Scenario
Master server Solaris 8 64 bit
We recently moved out catalog from local disk to SAN attached LUN, since
then the catalog backup is taking hours compared to what is used to.
We decided to take a copy of the catalog within a NBU policy to see the
results, as this would make full use of bptm and use the NBU buffer
setting config. The backup flew through fine confirming our SAN
infrastructure is sound.
I have tailed the bpbkar log when a catalog is running and it literally
chugs along, it seems as though the buffer it is filling is tiny as the
amount of data before pausing is tiny.
Does anyone have any suggestions or could point me in the right
direction? I get the feeling that this might be OS related somewhere as
we have another identical production system that also had its catalog
moved to a LUN and we have no issues what so ever with it?
Thanks
Dave
