Verifying The Device Operating Status; Preparing The Upgrade Images; Identifying The Issu Method; Verifying Feature Status - HP 10500 Series Configuration Manual

Verifying the device operating status

Verify the following items:
• Use the display device command to verify that no cards are in Fault state.
Use the display mdc command to verify that all MDCs are in active state.
•
Use the switchto mdc command to verify that no automatic configuration process is in progress. If
•
the message Automatic configuration is running, press CTRL_C or CTRL_D to break. appears, an
automatic configuration process is in progress. To perform an ISSU, wait for the process to complete,
or abort the process. For more information about automatic configuration, see "Using automatic
configuration."

Preparing the upgrade images

1. Use the dir command to verify that all MPUs have sufficient storage space for the upgrade images.
Use the display mdc resource command to verify that all MDCs have sufficient storage space for
the upgrade images. If the storage space is not sufficient, delete unused files by using the delete
/unreserved file-url command. If the files to be deleted are useful, back up the files before deleting
them. You will be unable to restore a deleted file if the /unreserved keyword is used. For more
information, see "Managing the file system."
2. Use FTP or TFTP to transfer upgrade image files (in .bin or .ipe) to the root directory of a storage
medium on any one of the MPUs.
Make sure upgrade image files for LSU1SUPB0(JG496A) interface modules use the -s.bin or -s.ipe
string as the file name suffix. Image files that have a different file name suffix cannot be used for
ISSU.
For devices that are using LSUM1SUPD0(JH198A, JH206) MPUs, transfer the upgrade image files
to the CF cards.

Identifying the ISSU method

1. Execute the display version comp-matrix file command for the upgrade image version
compatibility information.
2. Check the Version compatibility list field.
If the running software version is in the list, a compatible upgrade is required.
If the running software version is not in the list, an incompatible upgrade is required.
3. Identify the ISSU method.
If a compatible upgrade is required, check the Upgrade Way field to identify the ISSU method.
For more information about ISSU methods, see
If an incompatible upgrade is required, check the end of command output for the Incompatible
upgrade string.

Verifying feature status

For service continuity during ISSU, configure the following feature settings:
