Veritas Volume Manager 3.x for Windows 2000

Refer to the latest EMC Support Matrix to determine which Veritas Volume Manager 3.x configurations are supported, and what service packs may be required.

!CAUTION

Configuring large numbers of device paths with Veritas Volume Manager can cause a Windows system to boot very slowly, and in some cases overrun the NTLDR boot-time registry size and halt.

Systems that are configured with more than 512 device paths (total paths to all LUNs) should check with EMC Customer Service before installing Veritas Volume Manager 3.x.

If using PowerPath with Veritas Volume Manager 3.0 with Service Pack 1, you must also make the following registry modifications before PowerPath devices will be available to the Veritas Enterprise Manager:

Use regedt32.exe to set the registry as follows:

HKEY_LOCAL_MACHINE\SOFTWARE\VERITAS\VxSvc\CurrentVersion\VolumeManager value name = ShowGateKeeperDevices

data type = REG_DWORD value = 0x1

HKEY_LOCAL_MACHINE\SOFTWARE\VERITAS\VxSvc\CurrentVersion\VolumeManager value name = ShowEmcHiddenDevices

data type = REG_DWORD value = 0x1

After completing these changes, reboot the host system.
