Using the Command View (CV) web user interface create VDISKS, create DR GROUP using the
VDISKS and present those VDISKS to the connected host. After a DR group is created set the
destination host access field as Read only using Command View GUI.
NOTE: In the Metrocluster environment, it is required that the destination volume access mode
of the DR group be set to Read only mode.
In some earlier Command View software versions, when a DR group is created, only the source
volume (primary volume) is visible and accessible with Read/Write mode. The destination volume
(secondary volume) by default is not visible and accessible to its local hosts. The destination volume
access mode needs to be changed to Read only mode before the DR group can be used and the
destination volumes need to be presented to its local hosts.
Using Storage System Scripting Utility (SSSU)
HP Storage System Scripting Utility (SSSU) is a utility to manage and monitor HP P6000/EVA
storage array. Using SSSU you can create VDISKS and DR groups to use with Metrocluster packages.
For more information about SSSU commands, see the sample input file available at:
$SGCONF/mccaeva/Samples/sssu_sample_input
The contents of sample input file are listed below. In the following sample file, DC-1 is the name
of the source array.
select manager 15.13.244.182 user=administrator pass=administrator
select system DC-1
set DR_GROUP “\Data Replication\DRG_DB1” accessmode=readonly
ls DR_GROUP “\Data Replication\DRG_DB1”
After you create the VDISKS and DR groups, run the following steps when copying and editing the
sample input file:
1. Copy the sample file sssu_sample_input to the desired location.
# cp $SGCONF/mccaeva/Samples/sssu_sample_input <desired location>
2. Customize the file sssu_sample_input.
3. After you customize the sssu_input file, run the SSSU command as follows to set the
destination Vdisk to read-only mode.
# /sbin/sssu “FILE <sssu_input_file>”
4. To create the special device file name for the Vdisk on P6000/EVA, after changing the access
mode of the destination Vdisk, run the /usr/bin/rescan-scsi-bus.sh command to
detect and activate the disks, and then run lsscsi command to display the configured disks.
NOTE: The lsscsi command is available in lssci package available in the respective
OS repository.
Creating the Metrocluster with Continuous Access EVA P6000 for Linux Map for the
replicated storage
The mapping file caeva.map is required to be present in all the cluster nodes for the Metrocluster
with Continuous Access EVA P6000 for Linux product to function. The mapping file caeva.map
contains information of the Management Servers as well as the information of the HP P6000/EVA
Storages and DR Groups used in the Metrocluster environment.
The Metrocluster with Continuous Access EVA P6000 for Linux product provides two utility tools,
smispasswd and evadiscovery, for users to provide information about the SMI-S servers running
