Device Busy Error while rmsf a disk

initin — Wed, 18 Jul 2012 04:51:49 GMT

Hi All,

On HP-UX 11iv3, I had created a Test PV, VG & LV befoe some days, Now I tried to remove it , Successfuly removed lv, vg & pv, in sequence.

Unpresented the lun from storage,

And When tried to remove device files, getting the following error.

#rmsf -H 64000/0xfa00/0x3d

Device at 64000/0xfa00/0x3d is busy. Cannot remove.

Do I need to delete the vDisk from storage before rmsf?

Please guide

Thanks in advance

Nitin

Something keeps this device busy. If you delete it from storage, it will turn to NO_HW, so you can use "rmsf -x" to delete the device.

Have you tried using the rmsf -H with the legacy hardware path?

Hi,

I used

#ioscan -funNC disk

# rmsf -H 64000/0xfa00/0x3d

The error I am getting is

Device at 64000//0xfa00/0x3d is busy. Cannot remove.

............................................................

#ioscan -funC disk |grep NO_HW

#ioscan -funC disk |grep t3d5

I m getting

disk 107 1/0/14/1/0/4/0.39.0.0.0.3.5 sdisk NO_HW DEVICE HP HSV300

disk 107 1/0/14/1/0/4/0.39.2.0.0.3.5 sdisk NO_HW DEVICE HP HSV300

disk 107 1/0/14/1/0/4/1.39.1.0.0.3.5 sdisk NO_HW DEVICE HP HSV300

disk 107 1/0/14/1/0/4/1.39.2.0.0.3.5 sdisk NO_HW DEVICE HP HSV300

do you mean to say #rmsf -H 1/0/14/1/0/4/0.39.0.0.0.3.5

and same for all 4 path?

Yes, you would do an rmsf for each NO_HW device.

Hi,

Even you might have tried "rmsf -u -H 64000//0xfa00/0x3d" which will Unbind a driver associated with a node corresponding to the hardware path 64000//0xfa00/0x3d.
