Re: remove the partition from the second mirroring disk

If you do not specify the '-w' option with idisk, it operates in read-only mode, making no actual changes at all.

 

The required command (as documented in HP's "When good disks go bad" PDF) is:

idisk -Rw /dev/rdsk/c0t2d0

 After this, the partition configuration will be gone, but the device nodes referring to the partitions will remain.

To make the device nodes reflect the new state of the disk, you'll need another command:

insf -e -H 0/1/1/0.0.0.2.0

Re: remove the partition from the second mirroring disk

Use "rmsf -x" to remove stale device files.

Hope this helps!

Re: remove the partition from the second mirroring disk

First I would check if the partitions are really deleted:

 

# idisk /dev/rdsk/c4t1d0

 

then remove the special files

 

# rmsf -H 0/1/1/0.0.0.1.0

 

then do an "ioscan" again.


Hope this helps!
Regards
Torsten.

Re: remove the partition from the second mirroring disk

Is this the same system?

 

http://h30499.www3.hp.com/t5/System-Administration/rx2660-bad-disk/m-p/5559539#M478567

 

 

Did you replace the disk meanwhile?

 

A new disk will get a new device file!

 

 

c4t1d0 becomes c4t2d0 after replacement!

 

 

Please clarify if the disk is replaced.


Hope this helps!
Regards
Torsten.

Hi,

 

Is this the same system?

http://h30499.www3.hp.com/t5/System-Administration/rx2660-bad-disk/m-p/5559539#M478567

 

No, this other server with 2 disk only, one bad disk.

 

Did you replace the disk meanwhile?

 

No i don't replace any disk

 

A new disk will get a new device file!

c4t1d0 becomes c4t2d0 after replacement!

Please clarify if the disk is replaced.

 

No this system has 3 disk, after i execute the # rmsf -H 0/1/1/0.0.0.1.0 command the disk disappeared and not available on ioscan, but i think after reboot will appear where i try with insf -e but nothing.

 

this output of ioscan before run the # rmsf -H 0/1/1/0.0.0.1.0 command.

Re: remove the partition from the second mirroring disk

If it is not shown in ioscan, the bad disk is likely dead. Try

 

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

 

with the appropriate sasd device.


Hope this helps!

Torsten.
