Hello new Forum
I realize my question will be start ou vague but here we go.
Got an Rx7640.
Runs a mostly patched Feb 2007 release of 11.31
is hooked up to an SSD-based storage via HP AB378-60101 4Gb 's.
Single LUN cooked though LVM, formatted with vxfs 6.
Problem : HBA usage shoots up to 100% while througput and IOPs stay ridiculously low.
Example :
sar -H 1 10

Data is being restored from fiberchannel tapes.
I need to find out where the pipes are jamming and I'm running out of ideas.
This is my first time working on this box so no prior knowledge as to if this used to work or not.
Anyone ever seen something similar ?
