9.3 Workflow to configure NE configuration rollback
1 Configure the storage location for the NE configuration rollback rescue file and
checkpoint files; see Procedure 9-11.
2 Create the NE configuration rollback rescue file; see Procedure 9-12.
3 As required, perform one or both of the following:
a Create the NE configuration rollback checkpoint files manually; see
Procedure 9-13.
b Configure scheduled checkpoint file creation; see Procedure 9-14.
4 As required, compare NE configuration rollback files with each other or with the
current NE configuration file; see Procedure 9-15
5 As required, perform one or both of the following:
a Revert to a previous NE configuration manually; see Procedure 9-16.
b Configure scheduled reversion to an NE configuration rollback checkpoint
file; see Procedure 9-14.
9.4 Workflow to perform a software upgrade on a 7210 SAS,
7450 ESS, 7705 SAR, 7710 SR, 7750 MG, 7750 SR,
7950 XRS, or OmniSwitch
1 Perform a preliminary check before you start the software upgrade.
i Manually verify the software image file checksums.
ii Verify that the device supports the new software.
iii Verify that there is sufficient space on the compact flash drive for the
software image files.
iv For NEs with redundant CPMs, verify that the boot environments are
synchronized by using the appropriate CLI command.
2 Download the software description file to a directory on a 5620 SAM client station.
3 Import the software description file; see Procedure 9-18.
Caution 1 — Before you perform an ISSU, review the appropriate
device release notice for more information about the device software
releases that support the ISSU. The software upgrade information in the
device documentation takes precedence over this procedure.
Caution 2 — Ensure that you regularly remove from the 5620 SAM
device software images that are no longer required, for example, by
deleting the images or by exporting to a file system. An accumulation
of device software images can dramatically increase the length of
operations such as backup, restore, and reinstantiation.
