Test the disks for SCSI-3 persistent reservations support.

[Prasad Joshi]

Hi All,

We have a setup wherin we have some HP-UX machines and some LINUX machines. Each of these machines is assigned some external luns.

Now, I want to test whether those disks support SCSI-3 persistent reservations support.

So, I need some commands or utilities from which I can find it out on all the platforms.

The servers which we have are

HP-UX 11.23
Suse Linux 9/10 and Red Hat Update 3/4.

On SUSE I know one utility called sg_persist which gives the same information But, I am not aware of other platforms.

Please inform, thanks in advance.

Thanks and Regards,
Prasad.

Shalom,

ioscan -fnC disk

Thats HP-UX.

lspci might help with RH, I'm an RHCE and don't know that one.

ioscan -fnC disk

Just gives the list of disk connected to the system but, I want to know which all of them are SCSi-3 PGR.

How could I check for it?

Well, you'll probably need to use cstm then and display full information on them.

Its part of online diagnostics and is free.
