Limit has been reached for the logical resource

[haiikal]

Hi Veritas,

Base on the info below, I need some help to understand what "Limit has been reached for the logical resource" means. This is a VMware snapshot backup. I'm having some issues with the number of LUNS connected to my media server, currently we have more than 400 LUNS on our vmware datastore, but it seems that 1 HBA port on a Windows Server 2008 can only detect 254 LUNS. Any suggestion?

The 254 limit of LUNs is quite typical, certainly of HBAs that aren't too recent.  In any case, it is probably not possible to manually get around an HBA firmware LUN limit, or an HBA driver LUN limit.

So, my only advive is... add another HBA.

Or add another media server as backup host...

Check the Resouce limit value of ESXserver in Host properties. Is that value set to 0 ?
