RE: Removing a failed drive permanently -- MIDRANGE-L

My curiosity was killing me so I opened a PMR earlier today - you're on
the right track with the FRU for the drive.  It gives them a pretty good
idea of the exact device without actually removing it and looking at the
sticker, although not always.  So if that isn't vague enough!  =)

I cannot define the 'x' either however some general observations from
Frankie and Frankie III's Disks. These are an eclectic pile of various
8, 17, and 35 GB Units.
On Frankie III:
For FC #6719 drives (35GB 10K) It appears that each different 'x' 
defines a different part number. I have -5 -7 and -9s with three
different part numbers.

For FC #6718 drives (17GB 10K) It appears the same. I have -6s and -7s
and two part numbers.

For FC #6717 drives (8GB 10K) It appears to ALMOST match. I have -3s and
-4s and while the -4s are the same part number some -3s are one part
number and others are a different part number. Hmmmm.

For FC #6714 drives (17GB 7200RPM) I have only -1s and they are all the
same part number.

On Frankie II:

He has FC #6717s I have -4s and -6s with the *same* part number and -3s
all with another part number.

Also FC #6713s with -3s and -4s each with unique part numbers.

Persuing a couple of systems with FC #4326 (35GB 15K) tey all have the
same -number and part numbers.

SO Based on this limited sample I would say the -x number generally
indicates a particular part number though not perfectly.

Wow!  Ok, trivia king - what's the type for?  I was looking for it the

other day, and I swore I've seen it before (like for example, 
6707-070-x
- what's x mean?) but I can't find it.

Model - Level - Type, I believe it what disks are represented as.  
Below are levels, IIRC.

And for the archieves - Disk models (may not be up to date):

030 - Unprotected or mirrored unit of a type not supported in HA 
controller parity set
      (520-byte device).

050 - Unprotected or mirrored unit of a type supported in HA 
controller parity set membership
      (522-byte device). Data compression inactive

060 - Unprotected or mirrored unit of a type supported in HA 
controller parity set membership
      (522-byte device). Data compression active

070 - Non-parity unit of parity set (full capacity, 522-byte device).
Data compression inactive

072 - Parity unit in parity set with 8 parity units (7/8 capacity, 
522-byte device). Data
      compression inactive

074 - Parity unit in parity set with 4 parity units (3/4 capacity, 
522-byte device). Data
      compression inactive.

080 - Non-parity unit of parity set (full capacity, 522-byte device).
Data compression active

082 - Parity unit in parity set with 8 parity units (7/8 capacity, 
522-byte device). Data
      compression active

084 - Parity unit in parity set with 4 parity units (3/4 capacity, 
522-byte device). Data
      compression active

If the drive is a model 070 then you can remove it from the ASP and

then

from the RAID set and then from the system. If it's any other 07x

number

then you need to remove it from the ASP, then end RAID, then remove

it,

then restart RAID.

I have replaced a failed drive with a new drive before but I'd like

to

pull one that I have no intention of replacing.  The system is at

only

20% and losing a 8GB drive will make virtually no difference in

overall

capacity (this is a seldom used test/development system).

Once I pull the failed drive, what do I run so that the RAID set

"knows"

that the drive won't replaced and that it has to rebuild the "lost" 
drive using the remaining drives in the set?

Thanks,
