Not able to remove device file for internal removed disk.

Hello All,

I am not able to remove device file of an already re-claimed internal disk on 11iv3.

#rmsf -H 64000/0xfa00/0x19e
Device at 64000/0xfa00/0x19e is busy. Cannot remove.

#rmsf /dev/disk/disk9552
Device /dev/disk/disk9552 is busy. Cannot remove.

Thanks & regards,
Kavita

Hi,
Are you sure this device is not used? If the device is in open state then you can't delete it.

>>an already re-claimed internal disk on 11iv3

was there any disk replacement ? if so in 11iv3 was it done on the same HW path or there was any change.

If this is not in use at all than try

Unbind a driver associated with a node corresponding to the hardware

rmsf -u -H 64000/0xfa00/0x6

Then remove with Critical Resource Analysis (CRA) report.

rmsf -c -H 64000/0xfa00/0x6

Manix,

Yes there was a replacement for the faulted disk on this device path, after replacement new device path generated for replaced disk & this old path remained so we tried to remove it but not ablt to.


cmihx002:/root# rmsf -u -H 64000/0xfa00/0x19e
rmsf: The given device doesn't support driver unbinding feature


Also rmsf -c -H 64000/0xfa00/0x19e, is not coming up with anything as it just hangs.

Thanks & regards,

Re: Not able to remove device file for internal removed disk.

Is this is SAS disk?


Did you follow the procedure for SAS disk replacements?

Maybe not.


Did you do the "pvchange -a n ..." command?

Hope this helps!

Re: Not able to remove device file for internal removed disk.

Such a sas disk always get a new device file, because it is another disk with another identifier.

After doing "pvchange -a n ..." and swap the disk, do

# sasmgr replace_tgt -D /dev/sasd0 -q old_dev=/dev/dsk/c1t4d0 -q new_tgt_hwpath=0/4/1/0.0.0.11.0


(with your own values!) to redirect the old device file to the new disk.


Then do the procedures as usual...

Hope this helps!
Regards
Torsten.
