Command View EVA, add host, type for polyserve

I've got a EVA 8100 with Command View EVA 7.X
and i like to add a disk larger than 2 TB to My HP Clustered gateway e.g. matrix polyserve CIFS server.
The host type in Command View is Windows. Windows can only use disks up to 2 TB.
Can anyone advise or point me to some documentation if its allowed to change the host type, and to which type, to get the disk over 2 Tb

Thanks in advance

Hi,
till now it is a EVA firmware limitation (1LUN max=2TB) but it can be done e.g. via the LVM (VG from multiple smaller VDISKs) on the host side if it is Linux...
the pain is one part of the reality

one additional,
HP Polyserve Matrix server can be implemented on Windows/Linux. Then the host type depends on the platform to which it is installed ...

Thanks for the reply. For now it is installed on a windows host.
If i understand it correct, it is impossible to make a lun bigger than 2 Tb with the EVA ?

yes, the 2TB LUN size is a EVA max (there are plans to give bigger LUNs in the EVA4400 future firmware releases)

Keep in mind that, like in a linux/unix operating system... you can combine multiple disks using the disk manager in Windows.


The question is how strapped are you with needing a LUN larger than 2TB vs. having a second LUN.

Personally, I am not sure if I would so such a thing... even on a linux/unix system.

I am sure the technology has advanced some since we used to do this on NT4 back in the day. ;o)

Hi Gerald,

You must use Windows host mode in the EVA.
Use the Polyserve volume manager to build a bigger volume containing several virtual disks from your EVA.

2T is usually a lun limitation of the OS.

Polyserve can use any lun the OS can see across all of the nodes.

Polyserve allows you to stripe a volume or put multiple luns together to form a volume > 2T.
