Adding A New Lu Via Dynamic Reconfiguration (When Using Sun Cluster) - Hitachi XP P9500 User Manual

# /usr/cluster/bin/scgdevs
21 When using, as a Quorum device, an HDLM device of an LU newly
.
recognized for the first time by HDLM driver, set up the Quorum device on
any node in the cluster.
The following shows an example of executing the command:
Check the device ID of the HDLM device.
# /opt/DynamicLinkManager/bin/dlnkmgr view -path
# /usr/cluster/bin/scdidadm -L
Set up the Quorum device:
# /usr/cluster/bin/scconf -a -q globaldev=d4
For cluster configurations with two nodes, execute the following command
to clear the install mode for the cluster:
# /usr/cluster/bin/scconf -c -q reset
22 Execute the following command to view the correspondence between
.
HDevName and iLU:
# /opt/DynamicLinkManager/bin/dlnkmgr view -lu
Check the correspondence between HDevName (the name of the logical
device file of the HDLM device) and iLU (the internal LU number) from
the execution results of the command, compare the correspondence with
the correspondence that took place before the HDLM installation, and
then re-register HDLM devices with the programs that will use them.
If you want to use volume management software to create a file system
on an HDLM-managed device, skip to step 24.
23 Perform registration for the disk device group.

If you are using VxVM, see
If you are using SDS, see
Registering HDLM Devices on page
If you are using SVM, see
Registering HDLM Devices on page
24 Create the file system and set up the global mount as necessary.

Adding a New LU Via Dynamic Reconfiguration (When Using Sun Cluster)

Note
¢
A new LU cannot be added via dynamic reconfiguration when you are
using VxVM, because the host must be restarted in order to use (in
VxVM) an LU that has been newly added to HDLM. Perform the
HDLM Operation
