Removal of Unnecessary hardware path

[Sharjeel Saleem]

Hi,
How i can remove old hardware path,there is no hardware attached anymore with it? but still diplay in ioscasn.

P.S: doubt in rmsf syntex.

Hi!!

Are there still 'devices' attached to the path? A reboot will clear anything there. System type?

thx

Try "rmsf -H".

for hw in `ioscan -fun|grep -i no_hw|awk '{print $3}'`
do
rmsf -H $hw
done

[Sharjeel Saleem]

No more hardware attached with it anymore.system type is rp3440.
(Not using anymore default SCSI port for TA5300,either scsi cable attached with dual card scsi card).

Not sure if I undestand your question. Can you provide the "ioscan -fn" output related to this?

[Sharjeel Saleem]

see the attached output...dont want to see any unclaimed hardware path.

[Torsten.]

status "NO_HW" means the hardware is removed?

Try

rmsf -k -H 0/1/1/1.1.0

for this entry for example:

scsi:wsio:T:T:F:31:188:200704:disk:sdisk:0/1/1/1.1.0:5 128 2 50 0 0 0 0 230 177 180 216 31 76 246 199 :1:root.sba.lba.c8xx.tgt.sdisk:sdisk:NO_HW:DEVICE:_NEC DVD_RW ND-3550A:3
/dev/dsk/c3t1d0



There is nor problem to only "see" these entries. After a reboot they are gone anyway.

Can you try with the below command ? Then do an ioscan ...

#rmsf -k -H 0/1/1/1.1.0

If the -k option is specified, the definition of all devices at that
hardware path are removed from the system, again without removing any
special files.

Thanks -ajesh

Hi again!

The NO_HW indicates that the OS is expecting hardware in that path, which is not there. Normally, things like bad hard-drives will report NO_HW. Like I said above, a reboot will clear the NO_HW. I know that the rmsf command will do so also, but my peers would be better prepared to give you the correct syntax.

Hope this helps.

[sachit patil]

use rmsf -h

[chris huys_4]

reboot the system.

The rmsf commands will not help. (and can make the problem worse)

dear Sharjeel

u can use rmsf -H then hardware path

first use ioscan -funC disk
then u will get hardware path
then use rmsf -H then hardware path
it will remove from u system
