Windows Using Large LUNs While in SCSI 2 Mode Association Sets DRM supports Windows 2000 hosts accessing large LUNs above D7 without offsets via Secure Path However all hosts using large LUNs on a controller in SCSI 2 mode must create a dummy LUN 0 and give access to this LUN HP also recommends that this phantom LUN be set to no write access Refer to the HP StorageWorks Secure Path for Windows Installation and Reference Guide for additional information 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 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 and then selecting Properties gt Autofailback gt Disable LUNs Lettered Incorrectly When LUNs are moved between hosts such as during a site failover or a site failback the LUNs may become out of letter order To prevent the out of letter order status follow the steps below 1 Before booting the Windows NT X86 host make sure all LUNs are failed over to one HSG80 path From the HSG80 CLI prompt issue the following command Restart Other Controller 2 Reboot the Windows NT X86 host 3 Use Disk Administrator to assign the correct drive letter so that the disks will now match the units on the controller 4 O2. 8 7P Configuration Guide I O Pause During Fabric Reconfiguration During a fabric reconfiguration you will notice a brief pause in I O functions on all servers connected to the fabric This brief cessation of read write operations is normal A fabric reconfiguration can be caused by switches starting up or shutting down and by the physical plugging or unplugging of fiber cables Controller Saturation High usage of many remote copy set and nonremote copy set LUNs has a serious impact on the performance of the remote copy set LUNs causing controller saturation and possibly starving a full copy operation A saturated controller condition begins approximately when idle time falls to 25 or less when viewed through VTDPY When this occurs you may see Aborted Command errors through the Command Line Interface CLI To prevent controller saturation m Avoid placing multiple heavy use loads on the controllers m Use the VTDPY screen to monitor controller idle time percentage Adjust load to maintain an idle time of 25 or greater RAID 5 Remote Copy Set Target Drop Under the following combined conditions RAID 5 remote copy set targets may be dropped m No write history log disk is configured and m Host I O is accessing the initiator remote copy set LUNs When both target controllers are shut down a full copy operation is triggered When the target controllers are restarted they will begin a 3 minute memory diagnostic While the me
