Good Day, I need some help guidance please? I recently upgrade my unity VSA firmware to UnityVSA-5.1.0.0.5.394.tgz.bin.gpg the sp is now booting to service mode? * Rescue Reason:    0x1200* Rescue reason for code 0x1200 - There is a problem with the system software on this Storage Processor (APPINIT). To attempt to correct this problem, first run Data Collection, and then try the following in order: Check all cables, reboot each SP, and reimage each Storage Processor (SP). If this does not resolve the issue, contact your service provider. I reviewed this fix and it does not seem to be working to resolve. [URL]
