Primary Symptom Secondary Symptom Suggested Action
loadrev or runrev
command fails
—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, issue 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.

Verify that the correct software is installed on the switch using
the commands described in the “Browsing the File System in
Backup Boot Mode” section in Appendix B, “PXM Backup
Boot Procedures.”
If the runtime software is not on the hard disk, copy it to the
hard disk as described in the “Transferring Software Files to
and from the Switch” section in Appendix B, “PXM Backup
Boot Procedures.”
If a typo is entered when initializing the switch, re-enter the
sysVersionSet command, enter the sysVersionShow command
to verify the correct setting, and then reboot the switch with the
reboot 2
1
command.
The switch displays the
following message: Please
run sysDiskCfgCreate.
The hard disk is formatted, but not ready for operation. Enter
the sysDiskCfgCreate command. For more information, see
