SAN16M-R SAN Router Installation And Service Manual 42
Requirements for upgrading firmware (4.6/4.7 to 5.0)
NOTE:
Migrating from EOSi version 4.6/4.7 to 5.0 involves certain
requirements that must be fulfilled before upgrading your firmware to 5.0
version.
The E/OSi 5.0 firmware size is larger than E/OSi 4.6 or 4.7 firmware
size and so, a second flash bank is required to enable the SAN router
to store two E/OSi firmware images such as a previous firmware
version and a newer firmware version. Due to this, there are some
constraints when the combination of E/OSi 4.6 or 4.7 or 5.0 are used.
• Bootrom should be upgraded to version 1.0.5 (For procedure,
refer
Upgrading bootrom (E/OSi)
on page 46).
• Primary partition (location #1) is recommended only for storing
images with E/OSi 5.0 version. You must migrate to E/OSi 5.0
from active secondary partition (location 2).
• Secondary partition (location 2) image can contain a previous
version such as E/OSi 4.6/4.7/5.0 but should be upgraded from
E/OSi 5.0 from primary partition (location 1). To achieve this,
download E/OSi 5.0 to primary partition (location 1), then
download to the secondary partition image (location 2).
• After migrating to E/OSi 5.0, if the secondary partition (location
2) contains either E/OSi 4.6/4.7 images and is active then the
firmware upgrade page in E/OSi 4.6/4.7 Element Manager will
be empty for the secondary partition (location 2). However this
will not have any impact in the functionality of the firmware.
Checklist for migrating to 5.0 version
To migrate to 5.0 version without any requirements, ensure that you
satisfy all these checklist items:
1. Read constraints and limitations before upgrading the firmware.
2. Choose the E/OSi firmware version you want to keep on the
secondary partition (location 2).
3. Upgrade the bootrom to v1.0.5.
4. Activate the secondary partition (location 2) and reboot the SAN
Router.
5. Upgrade the primary partition (location 1) with the E/OSi 5.0
firmware version.
