EMC Fibre Channel Storage-System Configuration Planning
Planning File Systems and LUNs with Shared Switched Storage
Part of a sample LUN and Storage Group worksheet follows.
Completing the LUN and Storage Group Planning Worksheet
As shown, draw circles around the disks that will compose each
LUN, and within each circle specify the RAID type (for example,
RAID 5) and LUN ID. This is information you will use to bind the
disks into LUNs. For disk IDs, use the form shown. This form is
enclosure_diskID, where enclosure is the enclosure number (the bottom
one is 0, above it 1, and so on) and diskID is the disk position (left is 0,
next is 1, and so on).
None of the disks 0_0 through 0_8 may be used as a hot spare.
Next, complete as many of the Storage System sections as needed for
all the Storage Groups in the SAN. Copy the (blank) worksheet as
needed for all Storage Groups in each storage system.
A storage system is any group of enclosures connected to a DPE; it
can include up to 11 DAE enclosures for a total of 120 disks. If a
