Log-Only Status Messages
Log-Only Status Messages
The following messages are not displayed on the system console; instead, they are recorded
in the system log file. Log-only status messages indicate error conditions affecting the UPS
Monitor's ability to monitor the PowerTrust units(s).
These messages are a subset of all the log-only status messages, and are listed here only if
the required ACTION involves a hardware check to be performed by qualified,
service-trained personnel.
MESSAGE
UPS LDEV <nnn> I/O Operation error: UPS device failed to
complete a Read I/O request in allotted time. The Read
request timed out. (UPSERR 0536)
CAUSE This is a software-detected error condition that indicates an error in the I/O
software subsystems that the UPS Monitor uses to communicate with
PowerTrust units. It could indicate a disconnected I/O cable or a PowerTrust
unit hardware malfunction.
ACTION
1. Check for proper connection of the PowerTrust unit I/O interface
cable at both ends.
2. Ensure that the PowerTrust unit is powered on.
NOTE: Even after correcting cable or connection problems, the system must
be rebooted before the software will attempt to resume monitoring the UPS.
MESSAGE
UPS LDEV <nnn> I/O Operation error: The actual Read data
transfer length in a UPS Read I/O operation was too short,
less than the minimum required Read transfer length. (UPSERR
0563)
CAUSE This is a software-detected error condition that indicates an error in the I/O
software subsystems that the UPS Monitor uses to communicate with
PowerTrust units. It could also indicate a hardware problem in the I/O
interface, or a PowerTrust unit.
ACTION 1. Check for proper connection of the PowerTrust unit I/O interface
cable at both ends.
2. If no I/O connection problem is found, call the Response Center.
NOTE: Even after correcting cable or connection problems, the system must
be rebooted before the software will attempt to resume monitoring the UPS.
