Hi,

We have just bought a HS23 Blade, that is installed into an S Chassis along with 5 existing HS21 blades.

Four of the existing blades all boot ESXi5.5 from the SAN and have read write access to 2 shared LUNs (ID 0 and 1) which are used as datastores for ESX.
We have Vcenter 5.5 and all the ESX hosts including the HS23 are part of that cluster.

The SCM is zoned correctly for bay 6, which is the bay that the HS23 is installed in, and the LUNs are displayed in ESX, but they are not showing as datastores.

There is 1 thing that i noticed, and thats the local drive is set to LUN 0 as well, but even when i remove access to LUN 0 from the SAN i cannot access the remaining LUN which is ID 1.

output from cli command "esxcli storage core path list"

and  "esxcli storage vmfs extent list" shows only 1 datastore

Volume Name     VMFS UUID                            Extent Number  Device Name                           Partition
--------------  -----------------------------------  -------------  ------------------------------------  ---------
datastore1 (5)  546f54ea-41b4c172-3c41-3640b5e87697              0  naa.600508e000000000188a83b0467e6c09          3


The only option i get is to create a new datastore, but thats not an option as i have production machines on those LUNs.

any help would be great.
