Moving Objects Between CDS Disk Groups
Use the vxdg move command to move objects between CDS disk groups. The disk group
alignment does not change. Refer to the VERITAS Volume Manager Adminstrators Guide for
examples of using this command.
Note This command is not supported for the Solaris OS on the X86 platform.
Changing Default CDS Setting for Disk Group Creation
You can change the default CDS attribute setting used in creating disk groups by modifying the
/etc/default/vxdg file.
Creating Non-CDS Disk Groups
Use the vxdg command to create a non-CDS pre-version 110 disk group:
# vxdg -T vers init dg disk_name=device_name
A pre-version 110 DG is given an alignment value equal to 1.
Note For a pre-version 110 DG, since the dg_align value is not stored in the configuration
database, it is set to 1 when the disk group is imported.
Disk groups with version numbers less than 110 are not supported for the Solaris OS on the
X86 platform.
Upgrading an Older Version Non-CDS Disk Group
You might want to upgrade a non-CDS pre-version 110 disk group in order to use new features
(excluding CDS).
Note You must always perform a disk group conversion (using the vxcdsconvert utility) to
use the CDS feature.
Use the vxdg command to upgrade the non-CDS pre-version 110 disk group:
# vxdg upgrade dg
Note After upgrading, the cds attribute is set to off, and the disk group retains an alignment of
1.
