Adding a disk to a VM guest

[Jason Shannon]

Hi

Can anyone spot where I'm going wrong?

I have a VM to which I want to add a new scsi device. This device has already been scanned into the host but when I issue the hpvmmodify to add in the device I get this..

disk 12 255/255/0/1.3 sdisk CLAIMED DEVICE HSV110 (C)COMPAQ
/dev/dsk/c11t1d3 /dev/rdsk/c11t1d3
ni-cr-dev-vm # hpvmmodify -P ni-cr-dev-vm4 -a disk:scsi::disk:/dev/rdsk/c11t1d3
hpvmmodify: ERROR (ni-cr-dev-vm4): Duplicate backing device '/dev/rdsk/c11t1d3'.
hpvmmodify: ERROR (ni-cr-dev-vm4): Unable to add device '/dev/rdsk/c11t1d3'.
hpvmmodify: Unable to create device disk:scsi:-1,-1,-1:disk:/dev/rdsk/c11t1d3.
hpvmmodify: Unable to modify the guest.
ni-cr-dev-vm #


Thanks to anyone who can help.

Looks to me like /dev/rdsk/c11t1d3 is already presented to some one.

Can you post a hpvmdevmgmt -l gdev

It looks like it has scanned in....

but it was me who presented the LUN and me who ran the hpvmmodify...

wel according to this message you have already assigned this device:
hpvmmodify: ERROR (ni-cr-dev-vm4): Duplicate backing device '/dev/rdsk/c11t1d3'.


Use hpvmdevmgmt and/or hpvmstatus to check if this already in use by a VM

Thank you very much.

These commands solved my problem.
