How to confirm RAID level for internal system disks

[Kuntal Gupta]

Hi experts,

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...

Have you tried any of the below command ?

#saconfig /dev/ciss
#sautil /dev/ciss

[Torsten.]

This server has internal SCSI disks only, no SAS.

For LVM mirrors use

# lvdisplay -v /dev/vg00/lvol1

and so on to see if there are mirrors.

[Hakki Aydin Ucar]

# swlist -l product|grep -i mirror
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..

[Anshumali]

For SAS, you can run like below:

# sasmgr get_info -D /dev/sasd0 -q raid

Thanks to all for their response.

Mr Shibin :

I didnâ 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 donâ 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.

[Anshumali]

vxprint and vxdisk list should give the information.... let me know if thats not what you are after...

If you have FOE probably you do not have a root mirror license to make mirroring the root,and check this out you can not see the product :

# 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

[Kuntal Gupta]

Thanks Mr Hakki Aydin.

># swlist -l product | grep B2491BA

No o/p

> # ioscan -fn | grep -i scsi

showing the combo (SCSI+ETh) cards, tape drives.

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

Thanks...
