Note The disk verification utility only logs discrepancies. It does not synchronize the differences.
Troubleshooting Discrepancies Between the Active and Standby Disk
If discrepancies are found by the disk verification utility, either:
• Locate the event logs that pertain to the affected database(s) for the indicated slot
or
• Enter the resetcd command to reset the standby PXM45 control card to resynchronize with the
active PXM45 control card’s disk.
If you provision connections while the verifydiskdb check command is running, discrepancies might
be flagged, even if the information between the active PXM45 disk and the standby PXM45 disk is
synchronized. To ensure an accurate log of discrepancies, wait for the verifydiskdb check to finish
running before you provision connections.
Managing Line Loopbacks
In a loopback test, signals are sent and then directed back toward their source from some point along
the communications path. Configure a line to loopback when you want to test interface usability. Use
the following procedure to test line signalling on an AXSM, AXSME, AXSME32 card.
Step 1 Connect a single line to the appropriate transfer and receive ports on the backcard you want to test.
Step 2 Establish a configuration session using a user name with SERVICE_GP privileges or higher.
Step 3 Enter the cc command to change to the appropriate AXSM card.
Step 4 Enter the dsplns command to display the configuration for all lines on the current card.
Step 5 Enter the addlnloop <-line type> <bay.line> <-lpb loopback type> command. described the possib;le
options for each AXSM card type.
