Creating disk groups with double protection level
When creating a disk group with double protection level on an array running XCS 10000000, a
minimum of 10 disk drives is required on the array. If the disk group contains fewer than 10 drives
and double protection is requested, only single protection level will be used.
If all the physical disks in the disk group are of the same capacity, double protection level is achieved
by reserving capacity equal to four times the capacity of a single disk. If the physical disks in the disk
group are of different capacities, double protection is achieved by reserving capacity equal to the
sum of the four highest capacity disks.

Citrix 5.6 host may require manual rescan
If you have a Citrix 5.6 host running Emulex 4 Gb/8 Gb HBAs in a direct connect configuration, you
may need to perform a manual rescan after adding or removing LUNs online.
Windows 2003 server requires hotfix
If the management server is running Microsoft Windows 2003, HP P6000 Command View may not
display any array. To resolve this issue, you must install a Microsoft hotfix. Go to the following link
for details and the hotfix download:
http://support.microsoft.com/kb/9451 19
If you are using the server for storage only, not as a management server, you do not need to install
this hotfix.
HP MPIO EVA DSM requirement
HP strongly recommends that you always install the latest version of HP MPIO EVA DSM on all Windows
servers. The available MPIO DSM has exhibited LUN path failures on rare occasions. These LUN path
failures were not observed with HP MPIO P6000 DSM version 4.02.00.
NOTE: If you use HP P6000 SmartStart to install HP P6000 Command View on the Windows 2003
or 2008 management server, HP MPIO P6000 DSM 4.02.00 and DSM Manager are installed
automatically.
You can download the latest DSM Manager and HP MPIO P6000 DSM from the following HP website:
http://www.hp.com/support/downloads

2. Under Storage Infrastructure Software, select Other Multi-Path Software-Windows.
