Partitions
24 physical drives
An example of RAID 0 configuration (QuickRAID0 4): 2 or more physical drives
into 1 or more Virtual Drives.
Virtual Drive 0 has been configured into two partitions: LUNs 1 and 2.
Each Virtual Drive 1, 2 and 3 is configured by default as one partition and
designated LUNs 3, 4, and 5
RAID 0 subsystem example:
4 Virtual Drives
VD1, L3
VD0
VD2, L4
VD3, L5
P1 L1
P2 L2
P0
P0
P0
may only be applied after Partition
configuration.
2 Each RAID group is a Virtual Drive. The array
assigns an ID to each Virtual Drive. (refer to
RAID Level 1
on page 55,
RAID Level 10
on page
61 and
RAID Level 5
on page 57 about how to
create Virtual Drives). Type
VirtualDriveInfo
[active]
to determine the Virtual Drive ID and
LUNs of any Virtual Drives already set up on
your array.
3Type
VirtualDriveInfo [planned] to determine
if any partitioning has been planned but not
completed. If a merge has been planned and
you want the merge, go to step 5.
4 You may create up to 16 partitions on any
single Virtual Drive, with no more than 127
partitions across the entire array. Type
PartitionSplit [Virtual Drive ID]
[Partition ID] [number of Partitions]
5Type
PartitionCommit
to create the partitions.
The array completes the configuration and
reboots. The planned configuration you have
entered becomes persistent and active.
6 The array completes the configuration and
reboots.
To merge partitions
CAUTIONCAUTION
You may lose the ability to access data
when you merge partitions. Either back up
the data to another storage area or only
merge partitions which are data-free.
1Type
PartitionInfo [active]
to determine the
current partitions and their IDs.
2Type
PartitionInfo [planned]
to determine if
partitioning had been planned but not
completed. If a merge has been planned and
you want that merge, go to step 4.
3Type
PartitionMerge [Virtual Drive ID] [Partition
ID|all] [<Partition Number...>]
to create a
planned partition configuration.
4Type
PartitionCommit
to merge the partitions
and make the planned partition configuration
the active configuration.
5 The array completes the configuration and
reboots.
