/dev/sda: read failed after 0 of 4096 at 0: Input/output error


I have installed RHEL AS 4 update 5 on a HP DL740 server and presented 1024MB from the SAN (EVA3000) to the server.

The server has two Qlogic HBA cards installed with

# less /proc/scsi/qla2xxx/0
QLogic PCI to Fibre Channel Host Adapter for QLA2340:
Firmware version 3.03.19 IPX, Driver version 8.01.07.25
BIOS version 1.45

I am seeing a lot of device I/O errors for sda. See below.

How do I fix these errors?

I get a lot of trouble with this sort of thing with a USB flash drive and a USB dvd-writer. Both are treated as scsi by the kernel. The problems seem to be the USB hub and the fact that the dvd thing needs twice the RAM that the computer has.

Does that inform the problem - probably not?
