dmesg Error (PE-6850, RedHat 4 AS, EMC CX-300, QLA2340)

[Florencio Queiroz]

Dear Sirs,

I have an error at start-up of my server and CX-300.

Hardware:
Server: PE-6850
Storage: EMC CX-300
Fiber Controler: QLA2340

Software:
O.S.: RedHat 4 AS Update 3
NaviAgentCli
PowerPath 4.5.0

Everything is working but the file dmesg shows an error.

SCSI device sdc: 665156543 512-byte hdwr sectors (340560 MB)
sdc: asking for cache data failed
sdc: assuming drive cache: write through
SCSI device sdc: 665156543 512-byte hdwr sectors (340560 MB)

Buffer I/O error on device sdc, logical block 5
Buffer I/O error on device sdc, logical block 6
Buffer I/O error on device sdc, logical block 7
Device sdc not ready.

I think the error is occourring because the NaviAgentCli and PowerPath 
is not up yet, so the server doesn't reach the storage CX-300 and the 
device /dev/sdc is not ready yet.

Is it true? Any advice?

Thanks
