Setting LU Mapping information
Hitachi AMS 2000 Family Copy-on-Write SnapShot User Guide
•
4. The following example releases a command device:
•
5. To change an already set command device, release the command
device, then change the LU number. The following example
specifies LU 201 for command device 1.
•
The Mapping Information is specified using Navigator 2. If no
mapping is done on the P-VOLs and V-VOLs specified in the CCI
configuration files when the Mapping mode is enabled, which means
the hosts cannot recognize the P-VOLs and V-VOLs, no pair operation
can be done on the P-VOLs and V-VOLs. Use LUN Manager if you want
to hide the volumes from the hosts.
Prerequisite
For iSCSI, use the autargetmap command instead of the auhgmap
command.
To set up LU Mapping
1. From the command prompt, register the array to which you want
to set the LU Mapping, then connect to the array.
2. Execute the auhgmap command to set the LU Mapping. The
following is an example of setting LU 0 in the array to be
recognized as 6 by the host. The port is connected via target
group 0 of port 0A on controller 0.
