calculate physical disk

Fauziah Mahdan — Thu, 23 Apr 2009 08:17:36 GMT

I check my Delivery Order to 1 server is 73x4 HD. When I run nickel I only saw to disk attached. How to check the details if there is more hard disk or resided in the machine?

/dev/vg00
/dev/dsk/c3t0d0s2
/dev/vg01
/dev/dsk/c3t1d0

Hi Fauziah,

Try using the command ioscan -funCdisk in order to list the disks and their hardware paths on the system.

Regards,

Mark

hi
you can use
#ioscan -fnC disk to list the hard disks connected to your system.

hi
#ioscan -fnC disk output contain the CD ROM disk also.

Dear Mahdan

one option is using ioscan -fnCdisk

another one i think is
print_manifest (disk layout)
The usage can be specified only if you provide the server details

Sajjad Sahir — Thu, 23 Apr 2009 09:47:47 GMT

Dear Fouzia

to see the disk

u can use ioscan -funC disk

also u can use print_manifesto command

please see the usage of print_manifesto commannd
print_manifesto | more

thanks and regards

Hi,

"ioscan -fnC disk" is the command but if you want to see the disk details then the command is "diskinfo /dev/rdsk/cxtxdx"

Dear Fauziah

>How to check the details if there is more hard disk or resided in the machine?

First you check the server physically whether the 4 hard disks are connected or not.
if it is connected then it will shown in the commmand "#ioscan -funC disk"

# print_manifest = this also shows your disk layout and other h/w devices.

hope this help for you.

#ioscan
#sam ---> disks and filesystems
#print_manifest ---> If you have ignite
#xstm
#cstm

#ioscan -fnC disk (identify physical devices)

#diskinfo /dev/rdsk/cXtYdZ (return physical size)

#pvdisplay /dev/dsk/cXtYdZ (show used, free amount of disk associated with LVM)

Try using cstm / xstm

Hi,

Check with

(1)ioscan -fnC disk

(2)strings /etc/lvmtab
(To check no of disk or pv in each volume group)

(3)lvlnboot -v vg00
(TO check primary bootable root disk in root vg)

Regards,
Subodh

You have for sure an Integrity server - what model?

I guess your server has a hardware RAID configured - so you can only see logical (not physical) drives.

Please post first

# model
# ioscan -fn

to check.

Fauziah Mahdan — Fri, 24 Apr 2009 01:06:40 GMT

I have check from nickel output and I found only 2 disk. BTW this is the result from few command:

You have 2 times "HP IR Volume" - these are hardware RAIDS (mirrored pairs)!

Check with

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

and you will see all your 4 disks!

No Problem at all.

Re: calculate physical disk

Fauziah Mahdan — Fri, 24 Apr 2009 05:40:09 GMT

Sorry I dunno how to read this.
That means each 2 disk in vg00 and vg01 are mirror? Or only the primary disk mirror?
I check space of each vg00 and vg01 is 72GB

Re: calculate physical disk

Torsten. — Fri, 24 Apr 2009 05:42:22 GMT

That means each 2 disk in vg00 and vg01 are mirror?

Exactly.

What you see are 2 mirrored disk pairs forming 2 logical drives (IR Volumes = integrated RAID).

Run the command above and you will see.

Suraj K Sankari — Fri, 24 Apr 2009 05:51:52 GMT

Hi,
Yes both disks are mirrored,
