“I/O error” is recorded in the syslog by the cable disconnection during the access to the Fibre Channel disk:

οWhen the Fibre Channel connected to the primary PCI module Cable is disconnected during the access to the Fibre Channel disk, logs may be recorded, which seem that “SCSI disk (/dev/sdd**)I/O error”(** represent numbers) occurred on the devices which are not running because the internal status managed by the OS and the actual status on the server side are different. The operations are not affected.

HASIPMI-related logs are recorded in the log:

οThe following event logs may be recorded during the system operation. These logs are recorded when the software that access to BMC could not receive response from BMC within a given period of time. There is no problem to the system by this warning.

A timeout occurred for waiting BMC response. Process = (Although Primary BMC is ready)

A timeout occurred for waiting BMC response. Process = (Secondary BMC is still running)

SCSI-related logs are recorded in the system event log:

οSCSI driver records mounting and unmounting of a module in the system event log, but these events do not affect the system. However, if they are recorded for over 5 minutes, contact your sales agent.
