Hi,
I'm trying to understand why one array has a wildly different
partitionsize value to the other...
fuj411:/root# vxdmpadm getattr arrayname IBM_SHARK partitionsize
ENCLR_NAME DEFAULTCURRENT
IBM_SHARK0 2048 2048
Hi William,
Thanks for the reply. Not sure how to get this track cach size?
What's confusing me most here is that the values are so different between
the two arrays. They're identical models set-up up the same and with the
same number of disks allocated to the servers - sorry, forgot to
DMP is most likely throttling things back due to an issue on a path:
I/O throttling is a mechanism by which Dynamic Multi-Pathing (DMP) temporarily
stops issuing I/Os to paths that appear to be either overloaded or
underperforming. There is a default I/O throttling mechanism in DMP based on
the
Phil,
I don't believe any DMP values are changed by vxconfigd automatically.
To be certain the partitionsize has not been manually changed,
Is VxVM command line logging enabled? run vxcmdlog -l to find out
If yes, look in /var/adm/vx/cmdlog for any vxdmpadm setattr commands.
Do you use vea? If
