Defining The Paths; Setting Up Virtual Machines (Vms) And Guest Operating Systems; Setting The Scsi Disk Timeout Value For Windows Vms - HP StorageWorks XP24000 Configuration Manual

1. Verifying operational status of the disk array channel adapters, LDEVs, and paths.
2.
Connecting the Fibre Channel cables between the disk array and the fabric switch or host.
3. Verifying the ready status of the disk array and peripherals.

Defining the paths

Use XP Remote Web Console to define paths (LUNs) between hosts and volumes in the disk array.
This process is also called "LUN mapping." In XP Remote Web Console LUN mapping includes:
• Configuring ports
• Enabling LUN security on the ports
• Creating host groups
• Assigning host bus adapter WWNs to host groups
• Mapping volumes to host groups (by assigning LUNs)

Setting up Virtual Machines (VMs) and guest operating systems

Setting the SCSI disk timeout value for Windows VMs

To ensure Windows VM's (Windows 2000 and Windows Server 2003) wait at least 60 seconds for
delayed disk operations to complete before generating errors, you must set the SCSI disk timeout
value to 60 seconds by editing the registry of the guest operating system as follows:
CAUTION:
Before making any changes to the registry file, make a back up copy of the existing file.
1. Start the registry editor: select Start > Run, enter regedit.exe, and click OK.
2. In the directory tree in the left panel, select HKEY_LOCAL_MACHINE > System > CurrentControlSet
> Services > Disk.
