Re: Removing a 9337 disk array under V4R4

["David Shea" <dshea@xxxxxxxxxxxx>]

Mike:

I've done this on v2r3, v3r1 and v3r2, but not V4.  You can remove several
disks at the same time.  The list time I did it, I went into DST, told it to
remove all seven drives from one 9337 array, it whirred for quite a while
(half hour?  hour?) before looking for some confirmation, then finished the
job sometime between 11pm and when I got up in the morning...

That was on a 9337-120 compatible drive - seven 1GB drives, and an E45.

I've never done two arrays at the same time.  But - better safe than sorry -
I'd do one at a time.

Good luck.
