Entire bus going up and down CX700
Hello, I have a CX700 and bus 1 keeps going up and down and by down I mean Unisphere will say everything is disconnected from the array. Drives, fans, power supplies, LLC's, everything all at the same time. Then a few minutes later everything will come back up except disk 1_0_0 and disk 1_3_14 (the first and last disks in the bus) will show "Powering On" as the disk state. A few minutes later everything will go down, and keep repeating. Any ideas on a solution? I've already tried reseating and replacing those 2 particular drives. Also when I sit and just watch the actual hardware, the behavior continues without any kind of fault lights or power losses or anything that would indicate a problem on the hardware itself.

I'd try re-seating the LCC's and the cables - you should probably power off the array before doing this. You may have a bad LCC on the bus. You can also try opening two Navisphere sessions - start one using the SPA IP address and the other using the SPB IP address, then watch the physical objects in the GUI to see if the same is occurring on both SP sides - that could help narrow it down to which LCC or which disk might be causing this.
The Event log may also provide some indication of what is happening.
This may require service to analyse the spcollects to see what's ocuring (I'm assuming you do not have a service contact on the CX700).
