Hy I have a problem with the supported luns of the hba of blade server
When I booted the blade I login to hba managment utility(control Q)
I do an scan and selected hba port 1, then I see only available the following lun id configuration.
Lun id 0 to lun id 7 supported
Lun id 8 to 14 not supported
Lun id 15 supported
Lun id 16 to 255 not supported

What does it mean?
I can use only 9 luns????
Thanks,
Eduardo

Hey, I suppose that is the Qlogic QMH2462?

Do you event want to boot from SAN? Or what are you trying to establish?

Checked the firmware?

Maybe there is some specific documentation available for this card. But it seems like a pretty severe limitation i that's the case. Also LUN0 for some arrays (like the EVA) is used for management and you cannot assign a data lun to that id.

Yes it is Qlogic QMH2462, I have the same hba on other enclosure with the same firmware and I haven't got problems.
The HBA is used on esx blade installation to have different datastores (luns).
In total I have only 8 luns available.
Lun 1 to Lun 7 and Lun 15
Thanks

But, if you're going to have esx datastores, then you're not booting from the SAN are you?
I doubt this applies, probably if you take one of your other blades then and boot into the FC HBA BIOS utility then you'll see the same.

Yes, i'm booting esx from san, the storage is netapp 3020, and I have the same behavior on other blade, the hba shows only 8 Luns available.
The enclosure is a c7000.
I don't know how I do to hba support more luns, what configurations must I check?

Those available LUNs may only apply for boot purposes.

Have you tried adding some more (small, test) LUNs and presenting them to the other ESX server as 8 or 9 to see whether it sees them?
