We would like like to download latest software version for

 

Product Information
HP A5120-48G EI Switch with 2 Interface Slots Software Version 5.20    

Have a look here.

Could you please refer to some HP documentation how to process upgrade on 4 switches in stack. We suppose that we can't avoid downtime becase stack is managed with one management interface in Device management/Software upgrade section.

We have two checkbox

-To upgrade the files of slave boards at one time

-Reboot after the upgrade is finished

Many thanks for quick answer on first question

Hi Lacko,

the flash memory 5120-EI switches can only handle one software image. Here's a manual method to update the software, you'll need a TFTP or FTP server to get the software from:

• Check status of IRF:

display irf configuration
display irf
display irf topology

• Check status of flash:

dir flash:
dir slotX#flash:

• If you want to be sure not to run into any issues with a corrupt flash file system:

fixdisk flash:
fixdisk slotX#flash:

• Delete old software image on master:

delete /unreserved flash:/a5120ei-cmw520-r2220p02.bin
If there is an old .btm file on the flash, delete it.

• Get software image, for example with TFTP:

tftp 10.10.10.1 get a5120ei-btm-621.btm
tftp 10.10.10.1 get a5120ei-cmw520-r2222p11.bin

• Delete & copy software image to slaves:

delete /unreserved slotX#flash:/a5120ei-cmw520-r2220p02.bin
If there is an old .btm file on the flash, delete it.
copy a5120ei-cmw520-r2222p11.bin slotX#flash:/
copy a5120ei-btm-621.btm slotX#flash:/

• Update bootrom on master and slaves:

bootrom update file flash:/a5120ei-btm-621.btm slot 1
bootrom update file slotX#flash:/a5120ei-btm-621.btm slot X

• Activate the new software image:

boot-loader file flash:/a5120ei-cmw520-r2222p11.bin slot all main

• Double check:

dir flash:
dir slotX#flash:
display boot-loader
save safely force

• Reboot switch stack:

reboot

Hopefully, you'll have an updated switch stack after some minutes.

Regards, Leonardo

 

Worth to mention that ensuring a proper MAD protection mechanism (ARP or BFD, as example) for the IRF would be of help in case of split brain occours.
