Just SPS Testing?

I have recently set up email alerts on my Sym VMAXe.

Since doing that, I am getting alerts at roughly 2 week intervals.

Here is a summary of the related events;

5/16 - Warning - SPS1A degraded (approx 20 minute later changed to Normal-Online)

6/2 - Warning - SPS1A degraded (approx 20 minute later changed to Normal-Online)

6/15 - Critical - SBS-2B Offline

6/15 - Critical - PS-A1 Offline

6/15 - Critical - PS-B1 Offline

These three occurred at the same time and then approx 20 minutes later, all three changed to Normal-Online.

The technician says are just normal Sym process for internal SPS testing and that no action is necessary.

Coming from a CX600/700 background, I guess I expect an internal battery test to make a reference to testing in the logs.

Also seems odd that the 5/16 and 6/2 events were just warnings but the 6/15 event is critical.

Can anyone comment if I am just being paranoid.. or do these events indicate more than just a SPS test?
