______________________ Note _______________________
A storageset must reside on one controller or the other. All the
partitions of a storageset must be on the same controller because
all the partitions of a storageset fail over as a unit.
The steps performed in Example 6–3 include:
1. Assigns a unit number to each storage unit and disables all access to
the storage unit.
2. Sets an identifier for each storage unit.
3. Enable selective access to the storage unit.
Example 6–3: Adding Units and Identifiers to the HSG80 Storagesets

HSG80> ADD UNIT D141 CROOT-MIR PARTITION=1 DISABLE_ACCESS_PATH=ALL
HSG80> ADD UNIT D142 CROOT-MIR PARTITION=2 DISABLE_ACCESS_PATH=ALL
HSG80> ADD UNIT D143 CROOT-MIR PARTITION=3 DISABLE_ACCESS_PATH=ALL
HSG80> ADD UNIT D144 CROOT-MIR PARTITION=4 DISABLE_ACCESS_PATH=ALL

Warning 1000: Other host(s) in addition to the one(s) specified can still
access this unit. If you wish to enable ONLY the host(s)
specified, disable all access paths (DISABLE_ACCESS=ALL), then
again enable the ones specified.

specified, disable all access paths (DISABLE_ACCESS=ALL), then
again enable the ones specified.
HSG80> set d131 ENABLE_ACCESS_PATH = !NEWCON68,!NEWCON74,!NEWCON76,!NEWCON77
Warning 1000: Other host(s) in addition to the one(s) specified can still
access this unit. If you wish to enable ONLY the host(s)
specified, disable all access paths (DISABLE_ACCESS=ALL), then
