SAN DISK raid level in AIX

Hello All,

Our servers having emc clarion for the data disks. Is that possible to see those san disks raid level from AIX ?

Am having AIX 6.1 and EMC clarion 5.5.


Regards,

I am not sure if i understand you correctly. If you mean that you want to see the underlying RAIDs from within the system the LUN is attached to: no, you can't. You can't because these are different logical levels of abstraction.

For the system where the LUN is attached to a "disk" is a disk, regardless from what hardware it is constructed. Virtually, the Clariion exports a (vSCSI) disk simply not telling the target system from what it is made of. The target system connects to this disk using a (virtualized) SCSI protocol. Basically, the traget system treats the disk like it would be a locally connected SCSI drive, not caring for what is "underneath" this abstraction.

I hope this helps.

Thanks Bakunin, Thanks for your reply. I got the below command to check the details of the SAN disk. From the below output we can get the raid details too.

Code:
Bound Thin Pool Name     : RAID1_FC

This is a name, not the actual value of a configuration. So you depend on the fact, that someone or some mechanism is setting the name accordingly.
So what Bakunin said is still true - you basically can't get that information directly.
