identifying the new disk.

[Indrajit Bhagat]

whenever a new disk is been attached to system, how can we get to know which one is an new disk.

[Robert-Jan Goossens]

Hi,

Run ioscan before you attach a disk and after you atteched the disk.

# ioscan -fnCdisk > /tmp/ioscan.001

Instert the new disk

# ioscan -fnCdisk > /tmp/ioscan.002

# diff /tmp/ioscan.001 /tmp/ioscan.002

Regards,
Robert-Jan

Compare the output of "ioscan -kfnCdisk" from before and after.

the easy method:

- compare ioscan -fn before and after


the smart and clever method:

- calculate the hardware path!

[Torsten.]

BTW,

if you assign a disk to a running system, you will most likely see **NO** device file for this disk - only the path.

hi,

run ioscan -nfCdisk. output for the new disk is without path disk. to see the new path disk, run "insf -H hardware_path".

>> "new disk is without path disk"

No, you will see the hardware path, but no device file if you attach the disk to a running system (device file will be created if you reboot the box or if you run insf).

[Hasan Atasoy]

after ioscan and insf
ls -lrt /dev/dsk/

newly created address are your new disks ..
be careful in any case.

hi,

using ioscan -kfC disk (this will be your original device) ioscan is read from kernel

now ioscan -fnC disk (this will detect a new device/scanning)

hope this help

ioscan and insf
ls -lrt /dev/dsk/

New disk would be listed in last.

Hope this would help !!!
