Storagetek 9940B drives and Sun 2G FCI with QLC driver problems

[colinjohnson]

I have a problem where I can write data out to a 9940B using the Sun 2GB X6767A FCI at about 30MBytes/sec but can only read back at around 300kByte/sec. The data type might have something to do with this as it's variable block size, not uniform block size such as a tar ( tar worksfine at around 25MBytes/sec write and read ).

I suspect I will need to set something in the qlc.conf but haven't got a clue what.....

Does anyone out there know how the set parameters in the qlc. conf ( or even set the parameters in the X6767A interface nvram through the nvramrc )????
