Restored operating system users retain the same group assignments and account expiry settings as in the backup system. All restored users are created with the default password abcd1234. You should change the default password immediately using the chpvcuser Command.
  • When you run the command powervc-opsmgr backup -c <clustername> or powervc-opsmgr restore -c <clustername> a health check is performed before initiating the backup or restore operation. If the health check is not completed successfully, the operation is not initiated. You must address the issue before attempting to run the command again. For backup operation, the health check is performed during every instance when the command is executed.
  • Starting PowerVC 2.3.3, a new check for LDAP validation is introduced for backup and restore operation.
