Chapter 7 Switch Operating Procedures
Verifying PXM45 Disk Data
Returning to the Original CLI Session
After you Telnet from switch to switch, enter the escape character to close all Telnet sessions and return
to the original CLI session. The default escape sequence is Escape, Q (uppercase Q). Press the Escape
key first, then press Shift-Q. If you specified an alternate escape character when opening Telnet sessions,
enter that character in place of Q.
For example, if you Telnet from Switch A to Switch B to Switch C, the escape character sequence closes
the Telnet sessions on Switches B and C, and displays the CLI session on Switch A.
Displaying a Telnet Trace
After you Telnet from switch to switch, enter the trace escape character to display a list of connections
you have established between switches. The default escape sequence is Escape, g (lowercase g). Press
the Escape key first, then press g. If you specified an alternate escape character when opening Telnet
sessions, enter that character in place of g.
The following example shows a sequence of Telnet sessions and the trace that documents the sequence:

Verifying PXM45 Disk Data
When a failure occurs before a write is complete, the data on the active and standby hard disk may not
match.
Enter the verifydiskdb check [-l <level>] [-s <slot>] [-p <pass>] command at the active PXM45 to
run the disk verification utility. Table 7-41 describes the possible options for the verifydiskdb check
command.
Note Cisco recommends that you run the disk verification utility during a time when there is the least activity
on the switch.
