How to identify disk types on HP Itanium

Shyam Moghe — Thu, 11 Mar 2010 13:10:02 GMT

Please can someone tell the command to identify the disk attached to HP ITANIUM 11.31 box is SAN LUN.
Basically we want to differentiate between local disk, DVD and SAN lun.

Have you tried "ioscan -fn C disk > output.lis

It should give enough info to identify internal disk (obvious by address); the DVD; and which disk is EMC's.

Just a thought,
Rita

In refernce to your below post

I could you have posted "ioscan -fnC disk" output are you referring to same server ?

>>Basically we want to differentiate between local disk, DVD and SAN lun<< what differents ? size ? HW manufacture info .. some thing like that ..?

you use diskinfo command to check that

# diskinfo /dev/rdsk/c0t0d0 -> OS vg00 disk which has been sliced into c0t0d0s1 c0t0d0s2 c0t0d0s1

# diskinfo /dev/rdsk/c1t0d0

# diskinfo /dev/rdsk/c2t0d0

If this is the same server, it has an internal hardware RAID "HP LOGICAL VOLUME" and an internal DVD. All other disks are on SAN.

Johnson Punniyalingam — Thu, 11 Mar 2010 13:36:56 GMT

also please take note as mentioned by >>Torsten.

device files will not change! which is important from "System point view"

hardware path decides about the order, which nothing related "System point view" so you no need to worry. only (device file important)

The rx3600 has 8 internal SAS disk bays.

Your servers has an optional P400 smart array controller, so you cannot see the disks directly, but the logical drives only.

Answered?

There is no "automatic" way to find this out.

You can be sure all disks behind an FC HBA are somewhere outside.

But you cannot be sure all SCSI/SAS are internal. Same for USB.

You need to know the server and read the ioscan.

Re: How to identify disk types on HP Itanium

Shyam Moghe — Thu, 11 Mar 2010 13:47:07 GMT

We know that the system has 8 SAN disks and one local disk and one dvd drive.

But we want to know this from the output of some command/s which can tell us dynamically which devices are SAN luns and which are local ones.
Using o/p of this command/s, some other code has to determine disks types.

Is there any such command/s?

Re: How to identify disk types on HP Itanium

Torsten. — Thu, 11 Mar 2010 13:50:34 GMT

No.

See my previous post.

There are some special tools depending on the array model, e.g. evainfo for EVA, xpinfo for XP, etc.

Re: How to identify disk types on HP Itanium

Johnson Punniyalingam — Thu, 11 Mar 2010 14:05:16 GMT

As mentioned on the earlier post, you cannot use HP-UX system commands

suspecting if my "physic power stronger" you are using EMC SYMMETRIX CX700 calirion storage ???

It would be better for all us by if you can provide the "diskinfo command output" which posted earlier.

>>But we want to know this from the output of some command/s<<

you need to install "powerpath" for EMC
using "powerrmt command" you can achieve it :)

Re: How to identify disk types on HP Itanium

Steven E. Protter — Thu, 11 Mar 2010 15:27:34 GMT

Shalom,

I use ioscan -fnC disk to get the devices and diskinfo to get the type.

Hello,

Most likely the internal disk is being mirror at the hardware level via the SAS controller. The "ioscan -fkNC disk" produces only the one internal drive.

Hi,
swlist | grep -i pow
confomr your having powerpath
if you have powerpath installed
you can get all san disk assinged using command
powermt display all
