A Solaris system may be booted from a SAN disk under the following conditions:
ufsrestorecommands can then be used to create a bootable SAN disk. For more information, refer to the Sun document Automating the Installation of an FC-Fabric SAN-Booted System at http://www.sun.com/bigadmin/features/articles/fc_fabric_san.html.
Veritas Volume Manager can encapsulate a bootable SAN disk provided that the disk is listed as being supported for this purpose in the Hardware Compatibility List (HCL) on the support site at http://support.veritas.com.
For some disk arrays, special hardware configuration may be required to allow a system to be booted from one of the LUNs in the array. Refer to the documentation supplied by the array vendor for more information. Having configured the disk array so that you can boot your system from it, you can proceed to encapsulate it using VxVM.
To migrate from an internal boot disk to a SAN boot disk
(Add or initialize one or more disks)from the vxdiskadm main menu, or the VEA to add the target SAN disk to the boot disk group (aliased as bootdg).
(Mirror Volumes on a Disk) from the
vxdiskadmmain menu, or the VEA to create a mirror of the root disk on the target disk.
Once you have booted the system from the SAN disk, you can mirror it to another SAN disk that has been added to the boot disk group.
If required, you can remove the plexes of the original boot disk by using the
vxplex command. For example, the following command removes the plexes
home-01 that are configured on the boot disk:
vxplex -o rm dis rootvol-01 swapvol-01 home-01
