Hi guys,

Does anyone know how can I determine if disk array used is EMC or XP?

Thank you.

If installed 'inq' will let you know if they are EMC drives.

Inq is probably under
/usr/emc/ECC/bin/inq

Use
ioscan -fnkCdisk

Look in the description field.
Bot will be different.

Bill,

Thank you for the info. I don't have any machines with XP/EMC disk arrays, do you know approximatelly what flags should I look for?

Thank you!

The Description field on the XP will be something like OPEN
and on the EMC SYMMETRIX (or EMC)

ie: XP
SCSI describe of /dev/rdsk/c11t0d0:
vendor: HP
product id: OPEN-E
type: direct access
size: 14226480 Kbytes
bytes per sector: 512
rev level: 0111
blocks per disk: 28452960
ISO version: 0
ECMA version: 0
ANSI version: 2
removable media: no
response format: 2
(Additional inquiry bytes: (32)34 .......

You should ask in the storage forums, I don't have mine available right now to check out.

Later,
Bill

Hi,

From my emc/xp systems:

#diskinfo /dev/rdsk/c3t11d3
SCSI describe of /dev/rdsk/c3t11d3:
vendor: HP
product id: OPEN-E
type: direct access
size: 14226480 Kbytes
bytes per sector: 512

#diskinfo /dev/rdsk/c7t0d6
SCSI describe of /dev/rdsk/c7t0d6:
vendor: EMC
product id: SYMMETRIX
type: direct access
size: 31426560 Kbytes
bytes per sector: 512

From my system with EMC Symmetrix:
# ioscan -fkC disk
Class I H/W Path Driver S/W State H/W Type Description
===============================================================
disk 62 0/2/0/0.0.0 sdisk CLAIMED DEVICE EMC SYMMETRIX

From Raj's post I'd gather you'd see "EMC SYMMETRIX" replaced with "HP OPEN-E".

One additional point ->

OPEN-E is just one of the many modes of LUN standards which XP gives. So, a diskinfo on every XP disk(LUN) out there will not necessarily show up OPEN-E. It could be OPEN-9, OPEN-K .. for eg: here is another one:

#diskinfo /dev/rdsk/c17t4d1
SCSI describe of /dev/rdsk/c17t4d1:
vendor: HP
product id: OPEN-8*4
type: direct access
size: 28702080 Kbytes
bytes per sector: 512

So, the parameter to look out for would be
vendor. If the vendor is EMC then it is a EMC array. If the vendor is HP, then it is a HP disk and then grep for the product id to find out whether it is HPdisk or a HP-XParray and so on.

Hi,
All sysadmin should visit their data centre atleast once :)
And if you have a good documentation system in your organisation then you can refer that.
