How to find the number of physical hard disks in the LUN of storage from server

Hai to all,

I need to get the information about the number of hard disks added in the lun which i am using for one of my volume group.

Is it possible for me to get the details through any option of xpinfo command as if i am using xp1200 storage.

i had provided xpinfo -i which gives five diffrent LUN numbers but all with the same target

Jestin,

This is a long shot, I do not have an xp array, never use one before, the xpinfo -x will give you more information. Take a look at that one to see if you find what you are looking for.

Regards,

Jaime.

IMHO you should use CV XP or the webconsole for the array. However, xpinfo will list an info like this:

Device File : /dev/rdsk/c4t0d0
...
Disk Mechs : R1408 R1508 R1608 R1708



Is this what you are looking for?

Hope this helps!
Regards
Torsten.

Under 11.23, you can use sam to get a clearer picture of the disks.

From the server side, you are restricted to see what has been provisioned (zoned) to this server as far as I can guess. xpinfo will not let you cross over the zoning boundaries. So, the answer will be NO you will not get the whole picture of the frame using xpinfo, unless the whole frame is attached to your server and nobody else.

As suggested above, to get the hardware picture of an XP frame, you will need the command-view station.

Still not sure if this is what you are looking for ...



However, try

# xpinfo -r

ACP RAID RAID RAID Disk
Device File Pair Level Type Group Mechanisms
===============================================================================================
/dev/rdsk/c4t0d0 1 RAID6 --- 1-3 R0002 R0102 R0202 R0302 R0412 R0512 R0612 R0712


or



# xpinfo -l

Device File : /dev/rdsk/c4t0d0 Model : XP24000
...

RAID Level : RAID6 RAID Type : ---
RAID Group : 1-3 ACP Pair : 1
Disk Mechs : R0002 R0102 R0202 R0302
R0412 R0512 R0612 R0712




Hope this helps!

Re: How to find the number of physical hard disks in the LUN of storage from server

This is a bit complicated and requires some knowledge about XP arrays. What positions do you get?




What do you **really** want to know and why?

Hope this helps!

Re: How to find the number of physical hard disks in the LUN of storage from server

Dear Torsten

Its very urgent for me to determine the no of hard disks used for a particular server in the storage as the customer is asking frequently for that.

i need to explain before them i had gone through the document

xp lun configuration and security manager user guide

please help me

Re: How to find the number of physical hard disks in the LUN of storage from server

Disk Mechs lists the positions of the involved disks.

But there are soooo many possibilities to "build" or define LUNs - you need to use the array management tools to get detailed information.

Without a deeper knowledge of XP arrays you will probably not understand what you see ...



Better to ask administrator of the array!

Hope this helps!

Torsten.
