What are you using to RAID your disks?
If it is an AIX provided piece of software this would have been better posted in the AIX list, if it is Veritas Volume Manager or LVM for instance or other multi platform software, then this list is as good as any.
(For Linux and AIX I believe)
Is what I would use to see what disks are in use, if this is a software RAID and the individual disks are visible to the operating system then this will show which disks are most loaded, you could run this, log the figures then do something to use the filesystem you are concerned about and see which disks are the busiest and more to the point which has the largest queue size (waiting transactions) and await time which are causing the bottle necks ups .

Solaris 9
We had a problem server where only root was not mirrored (before my time). When I tried to mirror it, the live root slice bailed with errors at 97% so it couldn't be mirrored.
It's a matched pair of boxes (nfs1 and nfs2) and they are interchangeable with regards to the NFS... (0 Replies)

I seem to be running into an issue with some drives I have attached to my solaris server. The drives are attached correctly, the partitions are arranged with fdisk, the ext3 filesystem is setup using mkfs, and finally the drive is mounted.

Hi,
More a Sun T5220 problem then a Solaris 10 problem, but perhaps someone had a similar issue.
For starters the output with 1 disk in slot 0 of the server.
It points to PhyNum 5, where I would expect PhyNum 0.
