move the units to the correct path.
Windows Using Large LUNs While in SCSI-2 Mode
DRM supports Windows NT 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 NT- X86 cluster configuration, all remote copy sets within an
association set must be placed in one cluster resource group.

NetWare Cluster Services (NWCS)
NWCS v1.01 SP1 is supported at the initiator and target sites. Stretch Clusters are not
supported at this time. A Stretch Cluster is defined as having a NetWare Cluster using
NWCS with cluster members located at both the DRM initiator and target sites.
NWCS supports both remote copy set and non-remote copy set LUNs.
Planned Failover/Failback with NWCS
When preparing the initiator and target sites for a planned failover/failback, use
caution when removing access to the LUNs at the initiator site. Removing access to
the split brain detector (SBD) partition, as well as the cluster volumes, without first
bringing down the cluster will result in server abends. To avoid cluster members
abending, issue the following command at the system console:
CLUSTER DOWN
You can also run ULDNCS.NCF at the system console for each cluster member to
unload Cluster Services completely.
