Re: [PATCH 1/7] aacraid: Greater than 2TB capacity support (Update)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Updated to change the if/else sections to switch statements.

Received from Mark Salyzyn from Adaptec.
Greater than 2TB capacity patch. 

There are a few adapters that are capable of creating devices with this large
of a capacity, but now that we have the large fib support in, the management
applications will be capable of generating them.  The problem is, once they are
created, the driver will not be able to access the devices correctly without
this patch.

Applies to the scsi-misc-2.6 git tree.
