Using Volume Managers on Top of Virtual Disks

This section describes using volume managers on top of virtual disks.

Using ZFS on Top of Virtual Disks

Any virtual disk can be used with ZFS. A ZFS storage pool (zpool) can be imported in any domain that sees all the storage devices that are part of this zpool, regardless of whether the domain sees all these devices as virtual devices or real devices.

Using SVM on Top of Virtual Disks

Any virtual disk can be used in the SVM local disk set. For example, a virtual disk can be used for storing the SVM metadevice state database, metadb(1M), of the local disk set or for creating SVM volumes in the local disk set.

Any virtual disk whose backend is a SCSI disk can be used in a SVM shared disk set, metaset(1M). Virtual disks whose backends are not SCSI disks cannot be added into a SVM share disk set. Trying to add a virtual disk whose backend is not a SCSI disk into a SVM shared disk set fails with an error similar to the following.

# metaset -s test -a c2d2
metaset: domain1: test: failed to reserve any drives

Using VxVM on Top of Virtual Disks

For VxVM support in guest domains, refer to the VxVM documentation from Symantec.
