Ch 5: System Upgrades Upgrading the Marathon Software If the Marathon software needs to be upgraded or "patched", there are several considerations. Before upgrading Marathon software, make sure that: • The Marathon CD that contains the new version of software is available • An MTC diskette made using the new Marathon software is done • All mirror copies are done. • There is up to 24 MB of free space on the each IOP and CE system drive. • Any necessary backups are completed • An appropriate amount of downtime (normally less than one hour) to complete the upgrade procedure has been scheduled. At that time, continue with Upgrading Marathon Software on the CE Operating System. • Additionally, if the array to be upgraded includes any Marathon hot fixes, check the Endurance 4000 Release Notes to determine whether the upgrade that you are applying includes support for that hot fix. If it does not, contact HP Support. • Do not apply hot fixes distributed for a previous version of Endurance 4000 software to Endurance 4000 Release 2.2. Be sure to review the release notes of any Marathon patch or upgrade thoroughly before starting any of the procedures. Because the detailed steps may change in any given release, the following is an overview of what an upgrade process will be like: In general, the CEs will be upgraded first and will include the installation of the new documentation, the installation of the latest VnR drivers and lastly the shutting down of the CEs. By shutting down the CEs a disk re-mirror can be avoided. Next, the IOPs are upgraded one at a time including adding the latest Marathon networking services and ending with the shutting down of the IOPs. WARNING When upgrading the Marathon software on the IOPs when the screen calls for the upgrade options, it is critical to select Restore Original Installation Parameters. Selecting Preserve only applies to special cases and may not work on some systems. Now that all nodes are off, the MICs can be flashed with the latest MTCflash utility that will be on the upgrade CD.

Upgrading the Marathon Software
If the Marathon software needs to be upgraded or “patched”, there
are several considerations.
Before upgrading Marathon software, make sure that:
•
The Marathon CD that contains the new version of software is
available
•
An MTC diskette made using the new Marathon software is done
•
All mirror copies are done.
•
There is up to 24 MB of free space on the each IOP and CE
system drive.
•
Any necessary backups are completed
•
An appropriate amount of downtime (normally less than one
hour) to complete the upgrade procedure has been scheduled. At
that time, continue with Upgrading Marathon Software on the
CE Operating System.
•
Additionally, if the array to be upgraded includes any Marathon
hot fixes, check the Endurance 4000 Release Notes to determine
whether the upgrade that you are applying includes support for
that hot fix. If it does not, contact HP Support.
•
Do not apply hot fixes distributed for a previous version of
Endurance 4000 software to Endurance 4000 Release 2.2.
Be sure to review the release notes of any Marathon patch or upgrade
thoroughly before starting any of the procedures.
Because the
detailed steps may change in any given release, the following is an
overview of what an upgrade process will be like:
In general, the CEs will be upgraded first and will include the
installation of the new documentation, the installation of the latest
VnR drivers and lastly the shutting down of the CEs.
By shutting
down the CEs a disk re-mirror can be avoided.
Next, the IOPs are upgraded one at a time including adding the latest
Marathon networking services and ending with the shutting down of
the IOPs.
WARNING
When upgrading the Marathon software on the IOPs when
the screen calls for the upgrade options, it is critical to
select
Restore Original Installation Parameters
.
Selecting
Preserve
only applies to special cases and may not work on
some systems.
Now that all nodes are off, the MICs can be flashed with the latest
MTCflash utility that will be on the upgrade CD.
