It is possible that the disks in question were previously used in a raid
configuration.  As such they won't configure as hdisks.  Go into diag,
service aids, ssa service aids and reformat them as AIX system disks.  You
can get the serial numbers from lscfg -vp output.  After that do a cfgmgr
and the disks should then appear in the hdisk list.

Al Barth

If weverything was installed correctly and you rebooted or ran cfgmgr,
then they should be there.  Look at errpt and see if any errors, most
likely
will be some if not cabled correctly.  Double check cabling would be
my first step.  It's easy to get the cabling on SSA wrong, you can
"cable out" part of the drawer.

This is an AIX question so may be off subject a little.

I just had a second SSA drawer installed with 16 disks, only 7 of them
seem
to be missing depending on how you want to look at them. LSPV shows this
for
those disks. I've never seen this before so I'm not sure how to
"initialize"
if you will to get them to show up in Smitty, can't see them there. I'll
be
using these for my disk pools and DB and Log mirrors.

Others show this:

hdisk26        000143405657922b    None

hdisk28        00014340565826e1    None

Thanks for the help. Oh, lsdev -Cc disk does show the disks.
