—The loadrev command is blocked when a previous upgrade has
not been completed with the commitrev command. Enter the
dsprevs command to locate the cards that are still being
upgraded.
For more information on a particular card, enter the dspcd
<slot> command and verify that the Current, Primary, and
Secondary software revision numbers are identical. If the
numbers are not identical, enter the commitrev <slot>
command.
Enter the dspcds and verify that the standby card is in standby
state. Also look for a -U or -D in the dspcds command display,
which indicates that the card is in the process of being upgraded
(-U) or downgraded (-D). The loadrev and runrev commands
are blocked whenever the standby card is not in standby state or
an upgrade or downgrade is in progress.
After restart, the switch
stops displaying messages
and does not display a
prompt.
