I don't think you can actually use 0FF on windows. FE is the highest usable number on Win2k3R2 AFAIK.

Sorry about this.... It seemed my 1st copy of the post didn't come through

For Emulex native drivers on Solaris:

The Solaris configuration file /kernel/drv/sd.conf should contain all Targets and LUNs that a user may want to access. Devices accessed via Emulex Fibre Channel adapters and Emulex driver can be up to 512 Targets with a maximum of 256 LUNs per target.

I'll go dig out what the maximums are for Sun Leadville driver too....

Conor,

I had a dim and distant thought lurking at the back of mind that said solaris can handle up to 512 but I wasn't sure if that was just wishful thinking.

Thanks for the help - makes my provisioning that little bit easier.

From doing a bit of "Googling" it seems that the Leadville driver is rumored to support a theoretical maximum of 16,000 devices/target... I can't find any actual documentation to support this at the moment... will keep looking!

Uhm... don't know. Dynamox should know, he's our Solaris guru... I think.

Cheers for the response and although I want to know about the LUN ID Maximums for all hosts, I really need to know what the max is for Solaris.

Yep - found it finally - Max number of Luns per target using Leadville driver...

The number of LUNS per target for QLogic HBAs has now been increased to support a maximum of 16K

HBA support 16K? Does the host support too??

I hope so

I've personally seen solaris hosts (with leadville drivers) using luns over 0xff (255). I guess they don't lie

I once saw a Solaris host as well

I thought with certain HBAs, there was a method in Windows to go as high as 511... I'm sure the HBA would have to do some sort of "masking" though for Windows to pick it up.
