How to confirm RAID level for internal system disks
HP-UX, 11.31, Base VxVM (revision 5.00),rx-8640.
Quarries:
1) how to confirm the internal disk types (SAS/SCSI etc)
2) System disks are mirrored, but how to confirm from SW side, I mean the commands to know the RAID level.
thanks...

Re: How to confirm RAID level for internal system disks
For LVM mirrors use
# lvdisplay -v /dev/vg00/lvol1
and so on to see if there are mirrors.
Hope this helps!
Regards
Torsten.

Re: How to confirm RAID level for internal system disks
to check if you have mirror-ux sw installed.
# machinfo
to get more details on disk type.
You probably have RAID 1 due to mirroring..

Re: How to confirm RAID level for internal system disks
Mr Shibin :
I didn├в t find any entry starting with ciss under /dev
Mr Torsten:
Yes, from the manual it is clear that rx-8640 contains SCSI disk, but sir how should I confirm this from OS side by command line?
I have mentioned that I am using VxVM.
Mr Hakki Aydin,
No we don├в t have mirror ux license, we have used vxrootmir command for mirroring the system disk and machinfo to know the disk type!!!!!!!! How?
Mr Anshumali,
We don't have SAS disk,
Thanks once again to everybody; I am expecting few more inputs.

Re: How to confirm RAID level for internal system disks
# swlist -l product | grep B2491BA
sory for machinfo is not suitable to see scsi information but, you can:
# ioscan -fn | grep -i scsi
OR
# echo "selclass type disk;info;wait;infolog"|cstm
too see detailed info for disk

In my previous post I have attached few things, you may have a look there.
