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 PORT SERIAL LDEV CTG H/M/12 SSID
R:Group PRODUCT_ID
sdh CL2-G 63528 15360 - s/s/ss 0100
5:01-09 OPEN-V
sdu CL2-G 63528 2755 - s/s/ss 000B S:
00001 OPEN-0V
sdv CL2-G 63528 2768 - s/s/ss 000B U:
00000 OPEN-0V
sdw CL2-G 63528 2769 - s/s/ss 000B E:
16384 OPEN-V
• R:Group : This displays the physical position of an LDEV according to
mapping of LDEV in the RAID storage system.
LDEV mapping R: Group

Example in Linux:
# ls /dev/sd* |./inqraid
/dev/sdh -> CHNO = 0 TID = 1 LUN = 1
