After doing a filesystem check: # diag sys fsck harddisk (which reboots
system), shutting down from CLI after reboot: # execute shutdown, then
modifying HD1 size setting to 520MB and powering back on, I was then
able to perform the firmware upgrade.
I' m having the same challenge and increasing Hard disk 1 space from
48MB to 520MB is not resolving it. From console, I see the flash space
is still only 48MB: FAZVM64 # diag system flash list ImageName Version
