Installation and Upgrade Procedures
Step 4 Execute the PXM newrev command:
newrev sm <SM slot#> <new-rev>
where:
SM slot# is the slot number of the VISM 2 and new-rev is the filename of the new firmware.
This command causes the VISM 2 to become the active VISM running the new-rev firmware. The
previously active VISM 1 changes to a “hold” state and is still running the old-rev firmware. The primary
and secondary firmware switches with the new-rev becoming the primary firmware.
Step 5 Execute the PXM commit command:
commit sm <SM slot#> <new-rev>
where:
SM slot# is the slot number of the standby VISM 1 and new-rev is the filename of the new firmware.
This command causes both VISM cards to run the new-rev firmware. At first, VISM 2 is the active VISM
with VISM 1 remaining in the hold state. After a short time, the cards switch automatically with VISM 1
becoming the active card and VISM 2 the standby card.
The two VISM cards are now back to their original condition except that both cards are now running the
new-rev firmware.
Step 6 Log in to the active VISM card and use the display commands (dspendpts, dspcasvar, etc.) to confirm
that the configuration has been preserved through the upgrade process.
It is also recommended that a further verification be performed by making some minor modifications to
the configuration, checking that the changes have been executed correctly, and then changing the
configuration back again. Proceed to the VISM Boot Code Upgrade Procedure with PXM1 Cards,
page 36.
Note If the VISM card is not part of a redundancy group, Step 1 to Step 3 are sufficient.
Installing VISM Software Updates with PXM1E or PXM45 Cards
Complete the following steps to update the VISM software when you are using PXM1E or PXM45 cards
in your MGX 8000 Series chassis:
Step 1 Log on to the active PXM1E or PXM45 card.
Step 2 Ensure that the VISM/VISM-PR card is in the redundant mode, where the active card is the primary
card.
Step 3 Use the savesmcnf command to save the existing configuration as a contingency plan.
Step 4 Use the loadrev sm-primary-slot-num new-rev command, where sm-primary-slot-num is the slot
number of the VISM/VISM-PR card you to which you want to install the new software, and new-rev is
the new firmware version number for the VISM software.
