Veritas Storage Foundation Portable Data Containers: Cross-Platform Data Sharing 5.0.1 Administrators Guide, HP-UX 11i v3, First Edition, November 2009

Note: You must also perform a disk group conversion (using the vxcdsconvert
utility) to use the CDS feature.
To upgrade the non-CDS pre-version 110 disk group
Type the following vxdg command:
# vxdg upgrade diskgroup
Replacing a disk in a CDS disk group
Note: When replacing a disk in a CDS disk group, you cannot use a non-CDS disk
as the replacement.
To replace a disk in a CDS disk group
Type the following commands:
# vxdg -k rmdisk disk_name
# vxdg -k adddisk disk_name=disk_access_name
The -k option retains and reuses the disk media record for the disk that is
being replaced. The following example shows a disk device disk21 being
reassigned to disk mydg01.
# vxdg -k rmdisk mydg01
# vxdg -k adddisk mydg01=disk21
For other operating systems, use the appropriate device name format.
Setting the maximum number of devices for CDS disk groups
To set the maximum number of devices that can be created in a CDS disk group
Type the following vxdg set command:
# vxdg set maxdev=max-devices
The maxdev attribute can take any positive integer value that is greater than
the number of devices that are currently in the disk group.
