Need EMC Symmetrix driver for AIX 5.3

Hi all,

I hope I'm putting my first post at this site into the right forum. I need help finding the EMC disk driver for AIX version 5.3. I have some new EMC disk presented to a backup server of mine, and right now the EMC hdisks show up looking like this in an lsdev:

hdisk495 Available **-**-** MPIO Other FC SCSI Disk Drive

This is an AIX 5.3 server.

I poked around EMC's site with no luck. I'm hoping someone here has had to dig these up before.

Sincere thanks,
C.J.

Why? its state is available, you need now make it useable as a PV:

chdev -l hdisk495 -a pv=yes

Thanks for the tip. That didn't seem to work, though. I was able to find the EMC driver for AIX 5.3 and get that installed. I was told that I then need to remove the EMC hdisks and run cfgmgr again to get them to pick up the new driver. When I run either the chdev or rmdev commands, I see this "device is busy" message:

root@********:/dev# chdev -l hdisk495 -a pv=yes
Method error (/usr/lib/methods/chgdisk):
0514-062 Cannot perform the requested function because the
specified device is busy.
pv

Do you know what I need to do to remove those devices?

Sincere thanks,
C.J.
