Storage hardware and firmware revisions, support?

» close window

The Question is:

 
I have an older VAX 4000/100 running VMS 5.5-2
and need to replace several of the existing RZ24
drives in the BA350 with larger RZ29 narrow
SCSI drives.  RZ29's weren't available at the
time the 4000/100 was qualified, but I believe
that it should work because the drive size is
well below the 8GB limit for VMS 5.5-2.
 
The drives that the RZ29's are replacing are not
system disks, but old DEC DBMS area, snapshot,
and after image files.
 
My questions are,
 
1. are there any ECO's for this old of a VAX,
which is not under maintenance, or revision
levels for the RZ29's that I should be
concerned of since the 29's had numerous
revisions?
 
2. Are there any heat problems with the 29's in
the BA350?
 
3. Does DEC have a larger drive solution that
would leap-frog the 4.3GB drive?
 
and I do understand that solutions to my
are probably not DEC supported because they've
never been qualified for this system, but a
confidient 'should-work' would be appreciated.
 
Best regards,
 
Barry Treahy
 
 


The Answer is :

 
  Please contact your local hardware support organization for assistance,
  the level of detail required here is well beyond what can be reasonably
  collected or provided via Ask The Wizard.
 
  There is a dual-speed fan ECO kit -- fans, air baffles, and other parts
  necessary to keep the disks from overheating and failing -- available
  for specific older BA350 enclosures, and dual-speed fans are required
  for RZ29 and similar disks.  Certain BA350 enclosures may not (do not)
  have backplane support for the necessary dual-speed fans.  Again, please
  contact your local hardware support organization for assistance.
 
  6 or fewer RZ29 disks will operate with the BA35X-HA power supply on the
  BA350 series, but 7 drives will require the BA35X-HF supply.
 
  You will want to be running the required firmware version for the RZ29.
