Procedure 9-22 To upgrade the ISA-AA MDA software
Perform this procedure to upgrade only the ISA-AA MDA software on an NE, for example,
when the new software includes new AA protocol signatures.
The following must be true before you attempt an ISA-AA software upgrade.
• You have a 5620 SAM user account with an administrator or network element
software management scope of command role or a scope of command role with
write access to the mediation package. See chapter 2 for information about
scope of command roles.
• The FTP or secure FTP credentials are configured in the NE mediation policy.
See the 5620 SAM User Guide for more information.
1 Perform the following steps.
i Verify that the device supports the new ISA-AA software.
ii Extract the isa-aa.tim and md5sums.txt files from the Alcatel-Lucent
software package to a directory that is reachable by the 5620 SAM. Ensure
that there are no other files in the directory.
iii Manually verify the software image file checksum against the file checksum
listed in the md5sums.txt file.
iv Verify that the device file system has space for the software image file.
v For NEs with redundant CPMs, verify that the boot environments are
synchronized by using the appropriate CLI command.
vi Configure the appropriate software upgrade policy, as described in
Procedure 9-1; apply the policy to the NEs that you need to upgrade.
Note 1 — You cannot use the procedure to upgrade between major
releases; only minor-release ISA-AA upgrades within the same major
release are supported.
Note 2 — An ISA-AA MDA software upgrade is an in-service upgrade that
does not require an NE reboot. Although the Software Upgrade
parameter in the associated software upgrade policy must be selected
for the image activation and upgrade to occur, the Software Upgrade
Options in the policy do not apply to an ISA-AA MDA software upgrade.
Note 3 — The 7450 ESS, 7750 MG, and 7750 SR support ISA-AA MDA
upgrades.
Caution 1 — Alcatel-Lucent recommends that you open a physical
console session on the device that you need to upgrade. The console
session allows you to monitor the upgrade and recover in the event of
an upgrade failure.
Caution 2 — Before you attempt an ISA-AA MDA software upgrade, see
the appropriate device release notice and the 5620 SAM Network
Element Compatibility Guide for information about the supported
upgrade paths. See section 9.1 for general ISSU information.
