CM: Displays the copy mode N: Non Snapshot S: Snapshot. For SMPL state,
this shows that pair-volume will be created as Copy-on-Write Snapshot. C:
Volume Migration
EM: Displays the external connection mode H: Mapped E-lun as hidden from
the host. V: Mapped E-lun as visible to the host ' - ': Unmapped to the E-lun
BH: Mapped E-lun as hidden from the host, but LDEV blockading. BV:
Mapped E-lun as visible to the host, but LDEV blockading B: Unmapped to the
E-lun, but LDEV blockading
E-Seq#: Displays the production (serial) number of the external LUN.
Unknown is shown as '-'.
E-LDEV#: Displays the LDEV# of the external LUN. 'Unknown' is shown as
'-'.
(4) Command for discovering an external volume via the device file
It is possible to discover the external volumes by using the inqraid
command.
Example in Linux:
# ls /dev/sd* |./inqraid -CLI
DEVICE_FILE
R:Group PRODUCT_ID
sdh
5:01-09 OPEN-V
sdu
00001 OPEN-0V
sdv
00000 OPEN-0V
sdw
16384 OPEN-V
• R:Group: This displays the physical position of an LDEV according to
mapping of LDEV in the RAID storage system.
