HP StorageWorks Clustered File System 3.2.1 Windows Storage Server Edition Setup Guide (February 2006)

Chapter 3: Setting Up HP StorageWorks Clustered File System 13
For Windows Storage Server 2003 SP1, HP Clustered File System
supports only MBR basic disks; GPT basic disks are not
supported. For MBR basic disks, you can use either primary
partitions or extended partitions with logical drives.
When you configure the cluster in step 11, you can create HP Clustered
File System membership partitions on the partitions that you just created.
If you are unable to create LUNs on your disk array, you can place the
membership partitions on regular disk partitions. You can use the
Windows Logical Disk Management utility to create the appropriate
partitions.
Partitions Containing Windows Filesystems
If you will be using an existing partition for a membership partition and
that partition currently contains a Windows filesystem, then that
filesystem must be destroyed. One method for doing this is to delete the
partition, and then recreate it. This is best done before multiple servers
have access to the disk. If that is not possible, all other servers with access
to the disk must be forced to recognize the changes, either by rebooting
all those systems, or by manually disabling the ports on the FibreChannel
switch that connect those systems to the SAN. If using the second
method, disable the ports before making the partition table change, and
then reenable the ports afterwards.
Changes to the Disk Partition Table
HP recommends that you do all necessary partitioning on disks that will
contain membership partitions before assigning the membership
partitions. It is best to do the partitioning before multiple servers have
access to the disk. If this is not possible, ensure that all servers having
access to the disk through the SAN detect the partition table changes
before continuing on with membership partition initialization.
This can be done either by rebooting the servers after you make the
partition table changes, or by manually disabling the ports on the
FibreChannel switch that connect the servers to the SAN. If using the
second method, disable the ports before making the partition table
changes, and then reenable the ports afterwards.
