ATTO Technology Inc. Diamond Storage Array Installation and Operation Manual
Configuring a partially-populated array
The simplest way to attain RAID Level 5 in a
partially-populated array (an array with three or
more sleds but less than 12 sleds) is to create one
RAID Level 5 group, with or without hot spare
sleds, encompassing all the available sleds by
using the CLI command
QuickRAID5 ALL
.
To set up a partially populated arrays, you must
have at least three sleds filling contiguous slots as
shown in Exhibit 6.4-4, beginning with the slot
closest to the management card.
Exhibit 6.4-4 Examples of RAID Level 5 configurations in partially-populated array with at least six sleds. Hot Spare
sleds are in the highest slot numbers.
To set up RAID Level 5 groups
1 Connect to Diamond Storage Array services via
the RS-232 port or the optional Ethernet
management services card (refer to
Accessing
the Array
on page 17). You should now be in the
CLI.
2 Continue with the CLI or access the RAID page
of the ExpressNAV interface (refer to
ATTO
ExpressNAV: Browser-based Interface
on page 25).
Note
Because the ExpressNAV pages take you
through this process easily, the following
instructions are based on the CLI commands.
Use these instructions as a guide in
ExpressNAV.
3 Decide the RAID Level 5 configuration you
want based on the number of sleds you are
using and Exhibit 6.4-4 above.
4Type set QuickRAID5 [2 | 3 | 4 | ALL]
5Type SaveConfiguration Restart to save the
RAID Level 5 configuration.
6A Ready prompt displays. You must zero all
drives and parity to make all RAID Level 5
drives coherent. Type RAID5ClearData al
l
CAUTIONCAUTION
This is a destructive operation: all
information stored on these drives is lost.
DO NOT interrupt power until the
RAID5ClearData operation has completed
(three to six hours).
