But I keep getting the same error message about disk pdisk15 and the adapter

Is there any further research I should do? or what could be a cause of this?

Looks like pdisk15 has failed, what more do you want to know?

Says it all really. The drive will need to be replaced.

To find out what simple hdisk it relates to, try ssaxlate -l pdisk15 (lower case L flag)

If it's in one of your RAID sets, then I regret I have no experience in those.

Hello.

Thank you both for your help Smilie I,m extremely new into this world of AIX and pseries.

You both agree that pdisk15 had died, but physically on the pseries why do I see all disk with green light?, if one of them is death, it should show with ligth off or orange ligth?.

Sorry if my question sound extremely akward Smilie I just want to know exactly what disk to replace.

Just found this one to (maybe) make sure, that pdisk15 is the culprit or soon to be one:

Code:
ssa_diag command 
Purpose
        To Run Diagnostic style tests to a specified device.

[Syntax, Description]

ssa_diag is found in /usr/lpp/diagnostics/bin and is invoked:

 ssa_diag -l pdiskX
or
 ssa_diag -l ssaX

additional parameters are:

 [-a] : which causes the adapter to be reset
if it is an adapter being tested. (This has no effect on a disk test)
 [-u] : which forces a disk reservation to be broken, if it is a disk
which is being tested. (This has no effect on an adapter test)
 [-s] : This can only be used with a disk device, and requests the output
of the power status. (This flag cannot be used with the -a or -u flag)

Output

if an error is detected, then a message such as:

ssa0 SRN 42500

will be sent to stdout. If there is no problem, then there is no message
sent to stdout.
A non-zero return code indicates an error, for which output will be sent to
stderr.

Power Status output (to stdout) is as follows:
        pdisk0 0                which means pdisk0 Power good
        pdisk0 1                which means pdisk0 Lost Redundancy
        pdisk0 2                which means pdisk0 Failed

Hello.

Thank you all for your help Smilie I did use some of the command line expose here, but unfortunately every time I tried to view pdisk15 output came with "Error on device" so, finally in "diag" it shows me that pdisk15 was on status "failed" and also it shows up the serial number of the disk, so now I know what disk it is in the enclosure. It still keeps a "green ligth on" but, if the system says it has failed i should trust the system instead of the disk ligth.

I will replace the disk and see how it goes....thank you all Smilie
