Oliver - 

Can not comment on the power lines but in regards to the 6718 FFF7 errors
you need to determine if the SRC is informational, statistical, predictive,
or permanent. My guess is that the SRC is statistical. 

What is happening with this error is the IOP (your SCSI controller) had a
temporary disk data error. I would recommend the following procedures.

1. Get current on CUMs, hipers, and individual ptfs. 
2. Analyze the sectors on the drive you just mentioned
3. Run a reclaim storage on your system. Keep in mind this process will put
your system in a restricted state and can be time consuming.

Subject: AW: Disk Failure


Hello,

I just checked our system logs - we have had 4 (four) 6718 drives fail since
April.
IBM measured some electric current leaks on our powerlines and blames the
failing drives on this. 

In our SST I just found another drive error (temporary) with code 6718 FFF7
- anybody know how serios this is (IBM says no problem - but the helpline
guy didn't even know about the internet news on these DASD problems :(

Regards,

Oliver
