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

# df -k

Use this procedure if you want to create a rootdg diskgroup on a single slice.

Remember that rootdg is needed for Volume Manager to start the daemons.

After this procedure vxinstall is no longer needed. Use vxdiskadm to create other diskgroups.

1. Install the software packages for Veritas Volume Manager.

2. Configure the slice as a virtual disk in the diskgroup rootdg
# vxconfigd -m disable (to kill the vxconfigd)
# vxdctl init (to initialise VxVm database)
# vxdg init rootdg (to create rootdg)
# vxdctl add disk c0t0d0s7 type=simple (IGNORE THE WARNING : Not in configuration database)
# vxdisk -f init c0t0d0s7 type=simple (to add a disk record)
# vxdg adddisk c0t0d0s7 (make a slice into a virtual disk)
# vxdctl enable (reread config in memory)
# rm /etc/vx/reconfig.d/state.d/install-db (remove placeholder file for vxinstall)

3. Reboot or restart daemons manually.

# init 6

4.Create other diskgroups with vxdiskadm

# vxdiskadm
