I have a strange problem. Tru64 will only see 89 luns presented from storage. When 1 more is added, it shows the new lun, but one of the old ones dissapear. It always only shows 89. Is there a known problem with this. I am using both 1GB and 2GB HBA's.
And uh... being curious, what are all those luns doing? Petabytes of storage, or perhaps lots of 'little' luns ( < 50GB ) ? If so, why not fewer large ones? If need be, carve them up in software with LSM?

The client has moved all these LUN's to another Tru64 Host and the problem is the same. It seems the problem originates from the storage side. Somebody mentioned that it could be the "entitlement" that maybe be set for 90 luns, but as it starts from 0, it will only go to 89...I personally think this IS the problem and await the storage engineer's feedback. Thanks a lot for the reply in any event.

Non sequitur
Those statements does not not compute. For all I know it could be a storage problem. Fine. But I don't see how moving the luns prove that. If the other Tru64 box runs the same unspecified version and has the same adapters, then if would present the some limitation. Right?
Could it be an HBA/driver restriction? It could be a Tru64 restriction, but I doubt it.
Do the Alphas have multiple HBAs (redundancy) and can you try to present the luns 50/50 using controller settings, or switch zoning?
