Planning LUNs and File Systems with Unshared Direct Storage

A sample LUN worksheet follows.

Completing the LUN 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 LUN sections as needed for each

storage system.Copy the (blank) worksheet as needed for all LUNs in

each storage system. A storage system is any group of enclosures

connected to a DPE; a full-fibre system can include up to nine DAE

enclosures for a total of 100 disks.

LUN Details Worksheet Use the following LUN details worksheet to plan the individual

LUNs. Complete as many of these as needed for all LUNs.
