Building Disaster Recovery Serviceguard Solutions Using Metrocluster with Continuous Access EVA P6000 for Linux B.01.00.00

CIMOM - Common Information Model Object Manager, a key component that routes information between providers
and clients.
This command adds a new record if it does not find the <hostname/ip_address> in the mapping
file. Otherwise, it only updates the record.
For Example:
# smispasswd -h <hostname/ip_address> -u administrator -n root/EVA -s
y
Enter password: **********
Re-enter password: ********
A new information has been successfully created
Deleting a Management Server
To delete a Management Server from the group used by the cluster, use the smispasswd command
with -r option. Example:
# smispasswd -r <hostname/ip_address>
The Management Server <hostname/ip_address> has been successfully removed
from the file
Defining HP P6000/EVA Storages cells and DR groups
On the node where access to SMI-S server is configured, define the HP P6000/EVA Storages and
DR Groups information to be used in the Metrocluster environment. The Metrocluster software
requires the internal device IDs to query the HP P6000/EVA storage states. The evadiscovery tool
is a Command Line Interface (CLI) that provides functions for defining P6000/EVA storage cells
and DR group information. The tool caches the internal device IDs in the caeva.map file by
querying and searching for a list of devices information. This type of caching improves the
performance when querying HP P6000/EVA storage states through the SMI-S whenever required.
To use the evadiscovery tool:
1. Create a configuration input file. This file will contain the names of storage pairs and DR
groups. A template of configuration input file is available at the following location for Red
Hat and SUSE.
$SGCONF/mccaeva/mceva.conf
2. Copy the template file to the desired location.
$SGCONF/mccaeva/mceva.conf <desired location>
3. For each pair of storage units, enter the WorldWideName (WWN). The WWN is available
on the front panel of the P6000/EVA controller or from the HP P6000 Command View user
interface.
4. For each pair of storage units, enter the names of all DR groups that are managed by that
storage pair.
5. Save the file.
Creating the Storage Map file
After completing the HP P600/EVA Storages and DR Groups configuration file, use the evadiscovery
utility to create or modify the storage map file.
# evadiscovery -f <desired location>/mceva.conf
