Re: rmsf

you need to do it on secondary path too

you'll still see entries in ioscan (probably with NO_HW status) until your next reboot.

Re: rmsf

Hi,

You should run it on all the paths. Because the device files are different for every available paths.
Best wishes,

Ganesh.

Re: rmsf

Hi:

Do both primary and secondary. They are different files.

Re: rmsf

Thanks to all.

or
Individually.
rmsf -a /dev/dsk/c127t2d4

rmsf -a /dev/dsk/c7t2d4

Re: rmsf

Why do you don't want to use rmsf -H?
It removes automatically all devices associated with this hardware path (primary path and all secondary paths, if there is more than one). I guess, this is what you want to do.

My 2 cents,

Re: rmsf



Dear Nath

in case of primary and secondry path u have to use rmsf -H on both they are different files'

second thing if u rebooting server it will get rid of all no need to remove
becuase it is not loaded kernel thats why
during booting kernel reads all possible devices connect to the system.

thanks and regards

Re: rmsf

hi,

i use this one-liner to remove luns showing NO_HW in ioscan:

for i in `ioscan -fnC disk | grep NO_HW | awk '{print $3}'`; do rmsf -k -H $i; done

but after a reboot they'll disappear.

Re: rmsf

Removing via rmsf will only remove the device files but ioscan will still show NO_HW.

The io devices tree is built at boot time and NO_HW entries cannot be dynamically removed without rebooting the system.

Re: rmsf

@Avinash: This is only true for ext_bus devices (like virtual SCSI controlers behind FC adapter). If you "rmsf -H" a disk,a tape or a NIC, it is gone... even with "ioscan -k" it is not visible anymore. If you issue an "ioscan" again (and the disk is still there), it will reappear.

My 2 cents,
Armin
