HSG80 Enterprise/Modular Storage RAID Array Fibre Channel Solution Software V8.7A for Windows Release Notes (AA-RH0QL-TE, July 2003)

Host Operating System Notes

Release Notes – HSG80 Enterprise/Modular Storage RAID Array Fibre Channel Solution

Software Version 8.7A for Windows

• StorageWorks recommends that you load software directly from the Solution

Software CD-ROM when installing drivers and running the Fibre Channel Setup

utility. You may experience problems on some systems if you first copy the

CD-ROM contents to a disk drive and then install from there.

• Windows 2000 dynamic volumes are supported in transparent failover

configurations or in Secure Path Version 4.0x multi-bus configurations.

• Cloning a Windows 2000 dynamic disk is allowed. However, either the CLONE

or the original can be mounted to the same host but not both.

Windows NT Specific Notes

• Fibre Channel software setup handles HszDisk and HS_Service installation. This

is sometimes referred to as HSZinstall in the documentation.

IMPORTANT: Do not use the Large LUN model with Windows NT Service Pack 5 under

any circumstances. Windows NT Service Pack 6A is the stated minimum for this Solution

Software.

• In a situation where you are replacing a server with another and using the existing

drives (storagesets) behind the array controllers, you may find drive to drive letter

mapping changes. During such a system changeover, remap drives to drive letters

using the Disk Administrator to restore proper access to your data.

• To delete the 8 MB EISA-type partition on new disk drives, as discussed in the

"Disk Device Support", page 18, create a unit and delete the partition in Disk

Administrator.

Windows 2000 Specific Notes

• New Universal Disk Drives (or units that are migrated from SmartArray

controllers usage) being configured into storageset members need to be initially

written to with DILX (a diagnostic utility on the HSG storage systems). DILX

only operates on units. Therefore, the new disks must be configured into a unit

prior to running DILX. Optionally, the HSUTIL format disk utility may be used

on a disk device.

• The Fibre Channel Setup utility installs HS_Service and HsxDisk software

components. These are similar to HS_Service and HszDisk in the Windows NT

setup procedure.

• There are two situations in which drive-letter remapping might occur and that

could affect access to data by programs you may need to run. The first situation is

one in which you replace one server with another. The second is a situation in
