• LU#: Defines the iSCSI/Fibre logical unit number (LU#) of the physical
volume on the specified target ID and port.
Note: In case of fibre channel, if the TID and LU# displayed on the
system are different than the TID on the fibre address conversion table,
then you must use the TID and LU# indicated by the raidscan command
in the CCI configuration file.
• MU# for ShadowImage (HOMRCF): Defines the mirror unit number (0 - 2)
to use the redundant mirror for the identical LU on the ShadowImage. If
this number is omitted, it is assumed to be (MU#0). The cascaded
mirroring of the S-VOL is expressed as virtual volumes using the mirror
descriptors (MU#1-2) in the configuration definition file. The MU#0 of a
mirror descriptor is used for connection of the S-VOL. The mirror
descriptor (MU#0-2) can be used in ShadowImage and Copy-on-Write
Snapshot. MU#3-63 can be used in Copy-on-Write Snapshot only.
Note: When you enter the MU number for a ShadowImage/Copy-on-
Write Snapshot pair into the configuration definition file, enter only the
number, for example, "0" or "1".

• MU# for TrueCopy/Universal Replicator/global-active device: Defines the
mirror unit number (0 - 3) if using redundant mirror for the identical LU
on TC/UR/GAD. If this number is omitted, it is assumed to be (MU#0).
You can specify only MU#0 for TrueCopy, and 4 MU numbers (MU#0 - 3)
for Universal Replicator and global-active device.
Note: When you enter the MU number for a TC/UR/GAD pair into the
configuration definition file, add an "h" before the number, for example,
"h0" or "h1".
