i just upgraded the firmware on a HP 2910al-24G Switch (J9145A) to version W.15.12.0011
- first i uploaded the new firmware as the primary image but when the switch was rebooted it did not use the new firmware.
- then i uploaded the new firmware as the secondary and rebooted and the new firmware booted up.
all settings that were before the firmware flash are still unchanged but i am unable to make any changes to the switch since it does not want to log in as administrator using the password that was used before the firmware update.
both web interface and telnet interface have this problem.
