Deleting a Management Server
To delete a Management Server from the group used by the cluster, use the smispasswd command
with the -r option. Example:
# smispasswd -r 15.13.172.12
The Management Server 15.13.172.11 has been successfully removed from the file
Defining EVA Storage Cells and DR Groups
On the same node, which the management server list was created, define the EVA storage cells
and DR Groups information to be used in the Metrocluster Continuous Access EVA environment,
and use the evadiscovery tool with the following steps:
1. Create a configuration input file. This file will contain the names of storage pairs and DR
groups. (A template of this file can be found in /opt/cmcluster/toolkit/SGCAEVA/
mceva.conf)
2. Copy the template file /opt/cmcluster/toolkit/SGCA EVA/mceva.conf)to
the /etc/dtsconf directory:
# cp /opt/cmcluster/toolkit/SGCAEVA/mceva.conf \
/etc/dtsconf/mceva.conf
3. For each pair of storage units, enter the WorldWideName (WWN) of the first and second
storage units. The WWN can be found on the front of the panel of the EVA controller or from
the Command View EVA 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.
The following is an example of the mceva.conf file.
Fill in the file as in the following example:

## This file provides input to the evadiscovery utility, ##

## Edit the file to include the appropriate data about the ##

## After entering all the desired information, run the ##

## Note: Before running evadiscovery, you need to use the ##

## The <storage_pair_info> tag represents the starting ##
