31 Deployment and Migration of Boot from SAN Configuration using Dell EMC OpenManage Enterprise version
3.3.1
5 Migration of Identities in OpenManage Enterprise
Migration is the process of removing the virtual identities from a failed server (source) and deploying them to an
identical target server.
As explained in the previous topics, the identities assigned by OpenManage Enterprise are virtual and are not
physically 'tied' to a server. In the event of a system failure, OpenManage Enterprise allows the user to migrate
these assigned virtual identities to an identical server to boot from the attached storage with a minimal impact on
operations.
Note: The new server which is selected for migration, should have an identical configuration to the source server
for the success of migration process.
As part of the migration process, the identities assigned to the source server are first reclaimed and then
deployed to the selected target server. Reclaiming is a process of removing the assigned identities from the
source server so that no two servers are assigned the same identities. Post reclaim, the source server is powered
off automatically by OpenManage Enterprise.
OpenManage Enterprise performs a seamless migration which results in the new target server booting into the
same LUN containing the critical workload.
To explain the concept better, the migration of virtual identities from an MX840c server (source) on the following
setup, is detailed.
➢ The sled is deployed with FC Identities and currently booted into ME array LUN via FC protocol containing
some critical workload.
➢ An identical MX840c is the target server to which the profile is migrated.
To migrate the virtual identities the following steps must be followed:
1. Go to the Details page of the server on which the template is deployed.
2. Select Migrate Profile under Configuration Profile.
