332 Chapter 4 Performing CCI Operations
(3) Command for confirming the status
It is possible to confirm the status for CC by using “-fe” option of the pairdisplay
command.
pairdisplay -g <group> -fe
-fe
This option is used to display the serial# and LDEV# of the external LUNs mapped to
the LDEV and additional information for the pair volume.
This option displays the information above by adding to last column, and then
ignores the format of 80 column.
This option will be invalid if the cascade options (-m all,-m cas) are specified.
Display example:
[Before execution of CC command]

[During execution of CC command, the progress is displayed in the copy %]
# pairdisplay -g horc0 -fe

CM: Displays the Copy mode
N
Æ Non SnapShot
S
Æ SnapShot.
For SMPL state, this shows that pair-volume will be created as SnapShot.
C
Æ Cruising Copy
EM: Displays the external connection mode
H
Æ Mapped E-lun as hidden from the host.
V
Æ Mapped E-lun as visible to the host
‘ - ‘
Æ Unmapped to the E-lun
BH
Æ Mapped E-lun as hidden from the host, but LDEV blockading.
BV
Æ Mapped E-lun as visible to the host, but LDEV blockading
B
Æ Unmapped to the E-lun, but LDEV blockading
E-Seq#: Displays the production (serial) number of the external LUN. ‘Unknown’ will
be shown as ‘-’.
E-LDEV#: Displays the LDEV# of the external LUN. ‘Unknown’ will be shown as ‘-’.
