Upgrade Restrictions And Guidelines; Preparing For The Upgrade - HP 10500 Series Configuration Manual

Upgrading method
Upgrading from the
BootWare menu
This chapter only covers upgrading software from the CLI without using ISSU.

Upgrade restrictions and guidelines

The switch starts up from the default storage medium. The default storage medium can be the built-in flash
memory, a CF card, or a USB disk. To change the default storage medium setting, access the BootWare
menu. For more information, see the release notes for the switch.
HP recommends that you store the startup images in the flash memory and specify the flash memory as
the default storage medium.
If the switch is starting up from a CF card or USB disk, do not remove the CF card or USB disk during
startup.

Preparing for the upgrade

1. Use the display version command to verify the current BootWare image version and startup
software version.
2. Use the release notes for the upgrade software version to evaluate the upgrade impact on your
network and verify the following items:
Software and hardware compatibility.
Version and size of the upgrade software.
Compatibility of the upgrade software version with the current BootWare image and startup
software image version.
3. Use the dir command to verify that all MPUs have sufficient storage space in the default storage
medium for the upgrade images. If the storage space is not sufficient, delete unused files by using
the delete command. For more information, see "Managing the file system."
4. Use FTP or TFTP to transfer the upgrade image file to the root directory of the default storage
medium on the active MPU (in standalone mode) or the global active MPU (in IRF mode).
For more information about FTP and TFTP, see "Configuring FTP" and "Configuring TFTP."

Remarks
Use this method when the device cannot start up
correctly.
To use this method, first connect to the console
port and power cycle the switch or PEX. Then
press Ctrl+B at prompt to access the BootWare
menu.
For more information about upgrading software
from the BootWare menu, see the release notes
for the software version.
IMPORTANT:
Upgrade an IRF system from the CLI rather than the
BootWare menu, if possible. The BootWare menu
method increases the service downtime, because it
requires that you upgrade the member devices one
by one.
