SFHA Solutions 6.0.1: Using vxcdsconvert to make Veritas Volume Manager (VxVM) disks and disk groups portable between systems for Cross-platform Data Sharing (CDS)

[Miranda_Zhao]

The vxcdsconvert command makes disks and disk groups portable between systems running VxVM with the Cross-platform Data Sharing (CDS) feature.

For more information on the CDS feature, see:

• Overview of the CDS feature
• Setting up your system to use CDS

You can resize the CDS disks to larger than 1 TB. For more information, see:

Dynamic LUN expansion

You can use the vxcdsconvert command to:

• Check whether disks and disk groups can be made portable (using the –A option).
• Convert disks and disk groups to be CDS-compatible.

For more information on the conversion procedure, see:

• Converting non-CDS disks to CDS disks
• Converting a non-CDS disk group to a CDS disk group

Note the following points:

• The vxcdsconvert command requires that disk groups be version 110 or greater.
• When a disk group is made portable, all disks within the disk group are also converted.
• Converting a disk group that contains RAID-5 volumes and logs fails, if there is insufficient space in the disk group to create an additional temporary RAID-5 log.
• The default private region size increased from 512 KB to 1 MB in SFHA release 3.2, and from 1 MB to 32 MB in release 5.0.
