Hi, Pat,

We're using the model 3230 array on our 996-500 running 5.0 with
PowerPatch 6.  This is the minimum recommended release level to support
these devices, although 5.5 PowerPatch 1 is the
"HP-officially-supported" version.  The only reason we went to the 3230
and not a 3500 was due to the access limitations for our data center -
i.e., elevator and entry door size.  We purchased the minimum
configuration - 134Gb raw (67Gb usable) using 4Gb devices and 512Mb
cache - with an upgrade path to ~400Gb raw.  The devices are connected
via 4 FW-SCSI channels, 4 devices per channel, and are configured as
HPDARRAY device types.  I believe that 5.5 will include a more specific
driver, but don't quote me!  :)

There are limitations for diagnostic support from the HP3000 if you run
the Symmetrix array on a C.50.06 (5.0/PP6) release, but all the
hardware support comes from EMC, anyway, and the dial-home capability
of the array is a real plus, as I'm sure you're aware.

From the documentation I have:

HP3000 hosts supported:  9x8, 9x9KS, 99x, 987RX, 987/150RX, 987/200RX
     987SX, 987/150SX, 987/200SX

Hardware requirements:   HP-PB 28696A FWD SCSI interface card
  (all above hosts)         (HSC FWD interface not supported)

check with your EMC and/or HP sales reps to verify any and all of it!

I hope this helps.

Hi listers,

Our site is currently using the Symmetrix disks (EMC) on HP-UX, and I'm
trying to do my homework before proposing them for our MPE systems. I have
read that they were available on both MPE/iX 5.0 and 5.5. Has anyone out
there installed the EMC disks (3500 or 3700) on either version of the OS
(preferably 5.0)?  If so, could you divulge some precious info? Like patches
applied, configuration issues, successes and failures.

Thanks,
