HP XP7 Storage - Manual (Page 208)

The addition of arguments for the host group to the raidscan command and the configuration
file means that it is not compatible with conventional CLI. Therefore, RAID Manager provides a
way to support CLI by specifying a host group in the port strings as follows.
•
CL1-A-GRP# (GRP# can be up to 127)
Specifying the host group for the raidscan command:
raidscan -p CL1-A-5
Specifying the host group for the configuration file:
#dev_group dev_name port# TargetID LU# MU#
ORA ORA_000 CL2-D- 1 4 1 0
ORA ORA_001 CL2-D- 1 4 2 0
If the port including a host group is specified to the port name, then a maximum of 255 LUNs can
be specified.
(2) Specifiable port strings
As a result, RAID Manager supports four kinds of forms for the port name.
•
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 can specify a host group with the port strings:
•
raidscan -p <port>, raidar -p <port>, raidvchkscan -p <port>
# raidscan -p CL2-D-1
PORT# /ALPA/C,TID#,LU#.Num(LDEV#....)...P/S, Status,Fence,LDEV#,P-Seq#,P-LDEV#
CL2-D- 1 /da/ 0, 4, 0.1(256)...........SMPL ---- ------ ----, ----- ----
CL2-D- 1 /da/ 0, 4, 1.1(257)...........SMPL ---- ------ ----, ----- ----
CL2-D- 1 /da/ 0, 4, 2.1(258)...........SMPL ---- ------ ----, ----- ----
(2) Command option including a host group
RAID Manager supports new option for the following commands in order to show a LUN on the
host view by finding a host group via the specified device.
•
raidscan -pdg <device>, raidar -pdg <device>, raidvchkscan -pdg <device>
# raidscan -pd g /dev/rdsk/c57t4d1
PORT# /ALPA/C,TID#,LU#.Num(LDEV#....)...P/S, Status,Fence,LDEV#,P-Seq#,P-LDEV#
CL2-D- 1 /da/ 0, 4, 0.1(256)...........SMPL ---- ------ ----, ----- ----
CL2-D- 1 /da/ 0, 4, 1.1(257)...........SMPL ---- ------ ----, ----- ----
CL2-D- 1 /da/ 0, 4, 2.1(258)...........SMPL ---- ------ ----, ----- ----
Specified device(hgrp=1) is LDEV# 0257
