Description

ZFS is a type of file system presenting a pooled storage model developed by SUN (Oracle). File systems can directly draw from a common storage pool (zpool).

Traditionally, Solaris based LUNs which are larger than 1TB in size, are configured with an Extensible Firmware Interface (EFI) labels (instead of Sun Microsystems, Inc "SMI" labels). 


NOTE: ZFS configured devices will default with an EFI disk label regardless of the physical LUN size.

Veritas Volume Manager (VxVM) in conjunction with Veritas DMP can be used to manage ZFS pools and any ZFS file system(s) that operate on those pools.

If enabled, DMP can be used as the multi-pathing driver for the management of ZFS pools.
 

Veritas requires the DMP tunable "dmp_native_support" to be enabled for Veritas DMP to manage the multi-pathing operations for the ZFS zpool:

# vxdmpadm gettune dmp_native_support
            Tunable               Current Value  Default Value
------------------------------    -------------  -------------
dmp_native_support                       on              off
