Host group control
The array has the defined host group in the port and is able to allocate host
LU every this host group. CCI does not use this host LU, and specifies by
using absolute LUN in the port. Therefore, a user can become confused
because LUN of the CCI notation does not correspond to LUN on the host
view. Thus, CCI supports a way of specifying a host group and LUN on the
host view.
Specifying a host group
1. Define the formats.
The way what CCI has addition of argument for the host group to the
raidscan command and the configuration file will not be able to maintain
the compatibility with conventional CLI. Therefore, CCI adopts a way
that supports in the form which specifies a host group in the port strings
as follows.
- CL1-A-GRP# (GRP# are up to 127)
* Specifying the host group for the raidscan command as follows:
•
* Specifying the host group for the configuration file
•
If the port including a host group is specified to the port name,
then maximum of specifiable LUNs are up to 255.
2. Specify the port strings. CCI supports four formats:
- Specifying the Port name without a host group
CL1-A
CL1-An where n: unit ID for multiple RAID
- Specifying the Port name with a host group
CL1-A-g where g: host group
CL1-An-g where n-g: host group=g on CL1-A in unit ID=n
Commands and options including a host group
1. Specifiable command for host group. The following commands are able
to specify a host group with the port strings:
·
raidscan –p <port>, raidar –p <port>, raidvchkscan –p <port>
•
raidscan –p
