(5) HORCM instance

It is possible to describe the original and target volume for the volume migration to MU# as another
group in horcm*.conf for HORCM instance of BC and /or Cnt Ac-S. Also, it is possible to define
the original and target volume for the volume migration in the horcm*.conf as HORCM instance
independent from BC/Cnt Ac-S.

Commands to control Auto LUN

(1) Command for Auto LUN

RAID Manager supports the volume migration by adding an option (-m cc) to the paircreate
command.

paircreate -g <group> -d <pair vol> … -m <mode> -vl[r] -c <size>

-m <mode> mode = cc

(can only be specified for Business Copy)

This option is used to specify the Auto LUN mode.

NOTE:

This option cannot be specified with "-split" option in the same command.

-vl[r]

The -vl option specifies "local", and copies from the local instance LU(P-VOL) to the remote instance
LU(S-VOL), an original volume as the local instance LU is migrated from P-VOL to S-VOL, and the
physical volume mapping between P-VOL and S-VOL is swapped after copied

The -vr option specifies "remote", and copies from the remotel instance LU(P-VOL) to the local
instance LU(S-VOL), an original volume as the remote instance LU is migrated from P-VOL to S-VOL,
and the physical volume mapping between P-VOL and S-VOL is swapped after copied.

-c <size>

This option is used to specify a track size of the case that copies paired volume at 1-15 extents.
In case of stopping Write to P-VOL and copying in a short time, the maximum value 15 is specified.
When this option is omitted, it uses a default value of (3) is used for track size.

(2) Command for discovering an external volume

It is possible to discover the external volumes by using "-fe" option of the raidscan command.

raidscan -p <port> -fe

-fe

This option is used to display the serial# and LDEV# of the external LUNs only mapped to the LDEV.

If the external LUN mapped to the LDEV on a specified port does not exist, then this option will do
nothing.Also if this option is specified, -f[f][g][d] option is not allowed.

Display example:

# raidscan -p cl1-a-0 -fe -CLI

PORT# /ALPA/C TID# LU# Seq# Num LDEV# P/S Status Fence E-Seq# E-LDEV#

CL1-A-0 ef 0 0 8 62496 1 19 SMPL - - 30053 30

CL1-A-0 ef 0 0 9 62496 1 21 SMPL - - 30053 32

CL1-A-0 ef 0 0 10 62496 1 22 SMPL - - 30053 33

E-Seq#: Displays the production (serial) number of the external LUN. E-LDEV#: Displays the LDEV#
of the external LUN.
