Recently I did head swap from FAS2240 to FAS8020. Initial DOT was 8.1 so I first updated DOT to 8.2 and then did headswap. All disks from FAS2240 shelf were relocated to external DS2246, so 8020 got exactly the same disks as 2240.
Today while looking for another customer system I noticed that no ASUP were present from new heads. I checked FAS8020 confugration and found that trasnsport was HTTPS while it was SMTP before. Then I found that both date and timezone were wrong; and to round it off, NTP servers disappeared.
Anyone has seen it before? I'm not exactly sure when it happened to be honest, but ASUP from FAS2240 are still present and stop at correct point in time. So I assume it has something to do with either update or head swap ...
Not everything was lost. E.g. SP configuration remained. Obviously everything that is based on configuration files remained as well. It really looks like only options were reset to default.
