Configuring an EMC Boot Device
Assigning a Permanent Boot Drive Letter for Windows NT
Installing Multipath
and Failover
Software
If you have installed failover software into a Windows NT 4.0 server, it is good practice to
1.Reassign all drive letters (including C: and the
higher available letters. (You must do this or C: will be taken once
it becomes available. After reassigning C:, you should receive a message requiring you to reboot for the new assignment to take effect.
2.Reboot the server.
On system restart you may receive virtual memory errors; this is normal.
3.Rename all drives to their original letters.
4.Reboot and make an ERD of the new configuration.
Multipath and failover software on the host can transfer control of storage system LUNs on a hardware failure in a LUN path.
Important: If the Navisphere Host Agent is installed, you must remove it before installing multipath and failover software. (Refer to the documentation that came with your failover software.) Reinstall the host agent after installing the multipath and failover software.
Follow these steps to set up the multipath and failover software:
1.Install the software as described in the your EMC ControlCenter Navisphere Management software, ATF, or PowerPath documentation.
2.Create and enable a zone for each additional HBA and SP port that will be supported by the multipath and failover software.
