Data Replication Manager HSG80 ACS Version 8.6-4P Release Notes

Platform-Specific Issues
Release Notes – Data Replication Manager HSG80 ACS Version 8.6-4P 19
Windows Using Large LUNs While in SCSI-2 Mode
DRM supports Windows 2000 hosts accessing LUNs above D7 without offsets via
large LUNs. However, all hosts using large LUNs to access LUNs on a controller in
SCSI-2 mode must be able to access LUN D0. Refer to the Compaq SANworks
Secure Path Version 3.1 for Windows Installation and Reference Guide
for additional
information.
Association Sets
In a Windows 2000 cluster configuration, all remote copy sets within an association
set must be placed in one cluster resource group.
Microsoft Windows NT
Additional Software Requirements
A list of the most current software for Windows NT can be found at the following
website:

Follow the Software Support Matrices link, then choose Windows NT.
Auto Failback
The Secure Path for Windows NT Auto Failback feature is not currently supported in a
Data Replication Manager configuration. Disable this feature by starting Secure Path
Manager, then selecting Properties > Autofailback > Disable.
LUNs Numbered Incorrectly
When LUNs are moved between hosts (such as during a site failover or a site
failback), it is possible that the LUNs may become “out of letter order.”
To prevent the “out of letter order” status, before booting the Windows NT-X86 host,
follow the steps below:
1. Make sure all LUNs are failed over to one HSG80 path. From the HSG80 CLI
prompt, issue the following command:
Restart Other_Controller
2. Use Disk Administrator to assign the correct drive letter so that the disks will now
match the units on the controller.
