by Attached below (after my sig) is a script I wrote that I find useful for
dealing with SSA drawers and loops. It has a couple of drawbacks: one
is that, unless you have diddled with the permissions of the commands in
/usr/ssa/disk/bin and /usr/ssa/ssaraid/bin, you must be root to run it,
and the other is that if you have multiple SSA adapters in a loop it
doesn't show the ones other than the parent you are starting from.
Since I know it well, I don't need an explanation of what it prints, but
it shows the pdisk, its position in the loop, the hdisk to which it maps,
the VG name owning the hdisk (or "None" if it has not been assigned to
a VG), the usage if it is not mapped to an hdisk (as would be the case
if it is a hot spare), the pdisk description, and the pdisk size if not
included in the description (this is the case for SSA160 devices - the
info is in the ODM but not the desc). This information is followed by
the output of "ssaraid -Izl <adapter>". I have another script, named
"ssalink", that just gives the first section for each adapter, but I
found that I needed both for full doc of the disks on the adapters.
Here is an example of its output:
