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.
The C-bit is required on Symmetrix director ports connected to systems
running VERITAS DMP. Users of EMC ControlCenter 5.1 and greater should
consult their ControlCenter documentation for directions on making this
change. Other users must contact their EMC representative to make this
change.
VERITAS Volume Manager 3.0
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.
