Veritas Storage Foundation 5.1 SP1 for Oracle RAC Administrator"s Guide (5900-1512, April 2011)

To extend the volume space on a disk group
1
Determine the length by which you can increase an existing volume.
# vxassist [-g diskgroup] maxgrow volume_name
For example, to determine the maximum size the volume oradatavol in the
disk group oradatadg can grow, given its attributes and free storage available:
# vxassist -g oradatadg maxgrow oradatavol
2
Extend the volume, as required. You can extend an existing volume to a certain
length by specifying the new size of the volume (the new size must include
the additional space you plan to add). You can also extend a volume by a
certain length by specifying the additional amount of space you want to add
to the existing volume.
For example, to extend the volume oradata_vol of
size 10 GB in the disk group oradata_dg to 30 GB:
# vxresize -g oradata_dg \
oradata_vol 30g
To extend a volume to a
certain length
For example, to extend the volume oradata_vol of
size 10 GB in the disk group oradata_dg by 10 GB:
# vxresize -g oradata_dg \
oradata_vol +10g
To extend a volume by a
certain length
To add a disk to a disk group
1
Determine the CVM master node in the cluster:
# vxdctl -c mode
2
Add the disk to the disk group:
# vxdg -g dg_name adddisk disk_name
Recovering from storage failure
Veritas Volume Manager (VxVM) protects systems from disk and other hardware
failures and helps you to recover from such events. Recovery procedures help you
prevent loss of data or system access due to disk and other hardware failures.
