Adding new disks to VIO


Map disks from storage manager to VIO host

Need to check the HMC to see which vhost is mapped to which LPAR
Select the LPAR > Hardware Information > Virtual I/O adapters > SCSI
Look for your host(s) in "remote partition" and note their 'vhost' number

Then log onto the VIO server as padmin.
• Then run the following to pick up the new disks
cfgdev (like config manager for VIO)
• Then map the new disks to the appropriate scsi adapters.
e.g.chdev -dev hdisk9 -attr reserve_policy=no_reserve
mkvdev -vdev hdisk9 -vadapter vhost3 -dev ha1_testdrive
mkvdev -f -vdev hdisk9 -vadapter vhost2 -dev ha2_testdrive
• If you make a mistake, you can delete with:
rmvdev -vtd ha1_testdrive
• Check the disks are present with
lsdev -type disk
Then log onto the LPAR and run cfgmgr
