3. SAN Functions
Server Linkage Functions
When using VVOLs, LUN#224 to LUN#255 (or LUN numbers that are recognized on the server
•
side) cannot be used as Virtual Machine File System (VMFS) volumes or RDM disks because
they are used for management.
Use ETERNUS SF Storage Cruiser to change the VVOL settings. Do not change any of the set-
•
tings from ETERNUS Web GUI or ETERNUS CLI, except to enable the VVOL function.
If a VVOL management information dedicated FTV fails because of errors such as a RAID group
•
failure, the VVOL management information dedicated FTV must be recovered by recovering
the RAID group, deleting and recreating the VVOL management information dedicated FTV us-
ing ETERNUS CLI, and by performing a backup (or synchronizing the VVOL management infor-
mation) using ETERNUS SF Storage Cruiser.
• If the VVOL management information dedicated FTV is formatted, performing a backup (or
synchronizing the VVOL management information), and recovery of the VVOL management in-
formation dedicated FTV using ETERNUS SF Storage Cruiser is required.
• If the FTRP has already been created and the maximum Thin Provisioning Pool capacity and
the chunk size are changed, before setting VVOL using ETERNUS SF Storage Cruiser, execute
the "set vvol-mode" command of ETERNUS CLI to enable the VVOL function. For details on the
chunk size, refer to
• When registering multiple FTRPs in a storage container, do not mix FTRPs with different chunk
sizes in the same storage container.
• To use VMware vSphere Replication, the controller firmware version of the ETERNUS DX must
be V10L80 or later.
