Get the disk info

[Hkandati]

Hi all

After storage team assigned disk to the server(HP-UX 11.00). I want to check the disk name assigned on to the sever.

Because I want the disk name to add to a particular volume grooup.

After you do an "ioscan -fn" (you can add -C disk, if you like). Next do, "insf" to create the new device nodes. You can then do a final "ioscan -fn" and you should see new device nodes associated with your newly detected disks (LUN's).

hi hkandati ;

get lun number from storage team ;
ioscan -funC disk > /before
ioscan -fnc
insf
ioscan -funC disk > after
compare befaore and after files and check the new device with

for example your new device is c4txdy
lun number must equal = 8*x + y

ioscan: libIO error from io_init: /dev/config - permission denied
------------------------
Got the above error when runned #ioscan -fnC disk. please help

[Hasan Atasoy]

are you in single user mode ?

[Hkandati]

I am multiuser mode

check the permissions for /etc/config.
Example:

crw-r--r-- 1 root sys 69 0x000000 Aug 18 2005 /dev/config

[Robert-Jan Goossens]

and you are root? And if you are root what are the permissions on the /dev/config file ?

$ ll /dev/config
crw-r--r-- 1 root sys 69 0x000000 Apr 17 2004 /dev/config

[IT_2007]

seems you may not root privilages. Login as root or use sudo to run ioscan -fn command.

What kinds of SAN is connected? EMC Symmetrix or Clariion or IBM Shark storage?

Depends on the type of SAN, you may have to use tools to query SAN disks. Once you see them then you can verify and initialize them using pvcreate.

[Torsten.]

IT is right, output for non-root user:

# /sbin/ioscan
ioscan: libIO error from io_init: /dev/config - permission denied.

But you can use

# /sbin/ioscan -fnkCdisk

(-k is also allowed for non-root users).

[Bill Hassell]

Thde ioscan command only works for ordinary users when you use the -k option. You must be root to run ioscan without -k, also called the discovery mode. If you have a lot od disks on the system, it will be difficult to find the new disk LUN.

So login as root, then run:

ioscan -fC disk
insf -e

and the new device files will be created. If you missed the insf messages, you can list the device files in date order:

ll -rt /dev/dsk

and the most recently created device files will be shown at the bottom of this list. You will have to be root to add this disk to your volume group.
