[j-nsp] Software Upgrade failures on EX4200

[Kamal Dissanayaka]

Hi Experts


Has anyone experience if error "*g_vfs_done():da1[READ(offset=4194304,
length=16384)]error = 6" *when upgrading EX4200 switches? The switch will
not boot after reboot though it suggest to reboot. We can manually boot it
through console and the see the partition that was backup before upgrade is
corrupted.

The issue with this is remote upgrades. Remote upgrades fails randomly and
some has to visit the sit to fix it. Is there any way fix it ?
