It is not OK.
I think the DS2405 is for clusters only with point to point supported -
but I think it works well.
Check the port settings and the speed settings on your server (fcmsutil
/dev/tdX)/ switchport (portshow/portcfgshow) and array / switchport. The
speed settings an the topology must be the same/matching per pair.
Can you post the output of these commands ?
Are the array attach redundantly ? - Test the performance again, with
the alternate path - If configured.

Ahm, you can only access the single harddisk at the ds2405, so you can't
make any luns.

Looks like a san or storage problem. Have you already installed the
latest FC, LVM and vxfs patches ?

What aboout your syslog ? - Any messages ? - Are the diskdrive in the
2405 ok, or have you some read/write errors ?
