Configuring site-based allocation on a disk group

Site-based allocation requires that each volume has at least one plex at each site that is registered in the disk group. When you set the site-based allocation requirement for a disk group, each volume created has the allsites attribute set to on, by default. The allsites attribute indicates that the volume must have at least one plex on each site that is registered to the disk group. For new volumes, the read policy is set to siteread.

If site-based allocation is not required, or is not possible (as is the case for RAID-5 volumes), specify the allsites=off attribute to the vxassist command.

Before setting site-based allocation on a disk group, be sure to meet the following requirements:

To turn on the site-based allocation requirement on a disk group

To remove the site-based allocation requirement on a disk group
