ESX 4.1 Cant Add SAN stroage.

[haris2887]

hi all..

i have an ESX4.1 server here and i am having trouble adding Storage from the SAN. (SAS storage)

the ESX host can see the storage is there, it reads the correct Size 2,233 TB and 7TB luns..

I have herd the Limit is 2 Gb, is this correct ?

If yes they what is the recommended type of config just mkae more Virtual Disks...

When i go to add them  i get the following error

Call "HostDatastoreSystem.QueryVmfsDatastoreCreateOptions" for object "ha-datastoresystem" on ESX "esx1.Domain.local" failed.

Here is the San Config

it does the same thing when i try to add the other LUN (7 TB one)

[DSTAVERT]

The maximum size of a LUN that can be presented to ESX(i) is slightly less than 2 TB (2TB minus 512 bytes). Create smaller LUNs.

Does that apply to SAS storage as well, i though it was only iSCSI..I am assuming the same limitation applies for both ESX and ESXi...

I am in the process of Creating a smaller Lun for testing , Hope fully it works

[DSTAVERT]

It doesn't matter whether it is iSCSI or Fibre Channel or local storage. ESX and ESXi are functionally equivalent

The only exception as far a datstore protocol is NFS which can be whatever size supported by the NFS server. Generally 16TB but higher is possible.

Also be aware of block size when formatting the datastore.  Refer to the following KB article http://kb.vmware.com/kb/1003565

Yep that was the problem..

Resized the LUNS and it works
