1. Make sure solaris can see the disk.
# df -k
verify the current size of the filesystem /u11 you want to grow
# format
make sure the new disks are labeled by solaris ( use type “0″ = autodetect size , and label the disk !)
2. Make sure Veritas can see the new attached disk.
# vxdctl enable
(allow VxVM to discover newly added disks — DISKS NEED TO BE FORMATTED FIRST using the “format” COMMAND !!)
# vxdisk list
(will list disks detected, disks marked as “error” have not been initialized for use by VxVM)
3. Intitialise the disk in a specific diskgroup.
# vxdiskadm
1. option one to initialiase the disk in the oracledg diskgroup
make sure to use the list option so you can see that the disk is in error ( not yet initialised by veritas)
Or use the following commands:
( # /usr/lib/vxvm/bin/vxdisksetup -i c2t32d8 )
(# vxdg -g oracledg adddisk oracled01=c2t32d8 oracled02=c2t32d9)
4. Find out how much space is available on these new disks.
# vxassist -g oracledg maxgrow vol_u11 oracled01 oracled02
` Volume vol_u12 can be extended by 57675776 to 314105856 (153372Mb)
(gets maximum size available for resizing volume on specific disks)
# vxassist -g oracledg growby vol_u11 57675776 oracled01 oracled02
(extends the volume as a stripe on these 2 extra disks)
NOTE sometimes you get error
vxvm:vxassist: WARNING: dm:oracle16: No disk space matches specification
vxvm:vxassist: WARNING: dm:oracle17: No disk space matches specification
(I believe this to be some sort of rounding error, because afterward the volume is extended !)
# vxresize -g diskgroup volumename +2g
This will make the filesystem 2 g bigger
# vxprint -vt
Disk group: oracledg
