hpvmmodify: Unable to dynamically delete device disk : please advice

vandevoort — Thu, 15 Mar 2012 11:50:03 GMT

HPUX 11.31 and HPVM 4.3 . and these Guests are in Controll by ServiceGuard 11.20 .

for a test in next order :

when added on a Guest a disk ,

hpvmmodify -P ahv012 -a disk:avio_stor::disk:/dev/rdisk/disk973

from hpvmstatus -P < Guest>

disk avio_stor 0 0 0 5 0 disk /dev/rdisk/disk973

on the Guest

create a Volume group - LV and File system on it mount .

wrote data to it .

umount file system vgexport ;vgchange -a n ; rmsf -a /dev/rdisk/disk19 ( the disk in this case)

tried to remove the disk from the Guest configuration :

On the Host:

hpvmmodify -P <Guest> -d disk:avio_stor::disk:/dev/rdisk/disk973
hpvmmodify: Unable to dynamically delete device disk:avio_stor:0,0,5:disk:/dev/rdisk/disk973 - Device busy.
hpvmmodify: Guest needs to be restarted (using hpvmstop followed by hpvmstart) for all changes to take effect.
ahv012: Distributed guests require equivalent modifications on all
HPVM servers to synchronize the change.

I do not know how dynamically remove this disk without a reboot of the Guest.

can someone help me with this ?

Thanks .

See HPVM Install and Manage (Admin) manual chapter 6.1.3.5:

Devices configured under AVIO Stor HBA for an HP-UX 11i v3 guest cannot be deleted (using
the hpvmmodify command) if the guest is online.

Run ioscan -kfNC tgtpath or ioscan -kfNC lunpath from the guest to obtain the
tgtpath or lunpath H/W Path for the device to be deleted. Remove the device by using
rmsf -H of the lunpath or tgtpath H/W Path from the guest and retry the hpvmmodify
command from the host.

Hi Stan,

what I read in the hpvm 4.3 manual : at 6.1.3.5

Devices configured under AVIO Stor HBA for a guest cannot be deleted (using the

hpvmmodify command) if the guest is at EFI.

But I am not at EFI but normal operational ..

our systems runs oracle databases on which hardly never allowed to shut down ..
