Chapter 28 Troubleshooting
Troubleshooting Commands
Verify if anyone has disable a partition.
Disabling the partition will not recalculate the end_lcn value. The end_lcn is recalculated by a card reset
or a
switchcc
or node rebuild.
cnfrsrc Fails with “Automatic Routing Management is Currently Using the Channel Space”
This error is indicates that there are Automatic Routing Management channels currently configured on
the space that the user wants for VSI.
For example: The BXM card supports 100 channels, with 50 of the channels configured for PVCs and
50 for VSI ranging from 51–100. Assume that the card has five connections on channel 45–49. Now
change the configuration of PVCs to 10. The command will work since only five are currently used. The
available channels on the card is now 40. If
cnfrsrc
is executed now to increase the number of VSI
channels, the command will fail, because channels 45–49 are currently in use.
To check if a specific connection is using a channel out of range, use the following procedure:
Step 1
Use the
dcct
command to verify the channel number (LCN) used by the connection.
Step 2
Get VSI end LCN using
dsplogcd
—field mc_vsi_end_lcn
Step 3
In normal conditions, the value of mc_vsi_end_lcn should be greater than LCN.
To check if any connection in the port or trunk card is using a channel out of range, use the following
procedure:
Step 1
Get VSI end LCN using
dsplogcd
—field mc_vsi_end_lcn
Step 2
Use the
dspchmap
command to display the map of LCNs used by connection in the card. In normal
conditions, no LCN higher than mv_vsi_end_lcn should be associated with an Automatic Routing
Management connection or trunk
xlat
.
Workarounds
: The only workaround is to delete the connections currently using the high end of the
channel range. On the trunk interface, causing the connections to reroute will likely cause the lower LCN
range to be used first. On the port interface, delete and readd the connection.
Troubleshooting Commands
A list of the troubleshooting commands are described in Table 28-5. For more information, refer to the
