Default Re: M4100 and amber disk lights

Slow responce in building arrays have been traced back to low ram. Turn off JVM, it requires 24 meg free. Mixed drives mfg can contribute to this too. Snap recomends that all drives be the same make, model, size, and firmware if possiable. The max deviation is suppose to be 2-3%. If new drives make sure all jumpers are set to Master.

What is the mfg of the drives. Snaps do not play well with EIDE drives. Compare the original drives specs , heads, sectors, cylinders ... I would like this info. It may be the way the unit calculates positions.

I think another user reported that it took 14 hrs to do a 3 disk array.

use "debug memory" from debug to see how much is available.

Using a 3 disk array with 1 spare, helps too.

Surprisingly the 4100 have the most problems with building arrays. This is due to some of the promise raid controllers are flawed.
