V4.0 564 alpha KZPSC-BA controllers with RZ29 disks standard SWXCR labels
Hi All ,
I have run a couple of diskx over the last couple of weekends
and have had weird/bad results from both. Digital are looking at the
problems but I REALLY need a hint. Can anyone help.?
The disks are on seperate controllers.
A write test I performed gave me nothing but read errors, no diagnostics.
The performance test gave me back results of like 3000 MB/sec. !!
I did have LSM installed the first time , but removed it for the
second attempt to make sure their was no buffering being performed
but still got the same results.
eg:
diskx -f /dev/re7c -o disk7c.out -p -n -S
