Part number for i2o controller on Alpha Server ES45 with Tru64UNIX.

[A.W.R]

Hi,

I have an Alpha Server ES45 running Tru64UNIX v5.1B.

It has an i2o RAID Controller.

/dev/rdisk/dsk0a: character special (19/18) I2O #0 "i2o_bs" disk #0 (SCSI ID #0) (SCSI LUN #0)

Please can snyone advise what the part numbers for these controllers were? It looks like a dual channel RAID controller, and it supports the 1" Universal disk drives.

THanks
Andrew

That would be a KZPCC
Probably an KZPCC-CA

It comes with management software like 'KZPCCAgent' which can spit out things like:

Dec 12 12:52:14 MASTER KZPCCAgent: Subsystem i2o0 : SWCC Warning -
Controller Event : The battery backup unit is considered BAD

The was/is an issue with V5.1B with a KZPCC.
The KZPCC appears as "bus i2o0" and "controller i2o_bs0 at i2o0".
The install fails when parsing "i2o" - see details below.

The v5.1b installation executes a script on the CD called "obsolete_hw"
which builds a list of installed options and checks to see if they are supported.

In the following extract from lines 88-91, sed parses bus and controller names and truncates them at the first digit found in the name.

88 cat /tmp/List$$ | sed -e 's/^#.*//' -e 's/^makeoptions.*//' \
89 -e 's/^config.*vmunix.*//' -e '/bus/s/[0-9].*//' -e
'/controller/s/[
0-9].*//' \
90 | awk '{print $2}' \
91 | sort -u >> /tmp/option_list$$


"i2o" turns into "i"
There is no supported option called "i", so the installation fails.

The solution for that is too easy:
When the installation reaches this point ...

Do you want to continue the Update Installation? (y/n) [n]:
... just answer "y"

The installation should complete successfully.

hth,
Hein.

Hi Andrew,

I agree with Hein, it will be a KZPCC, if you've got two channels, then I'd guess as at DS-KZPCC-CE.

It's actually an Adaptec based RAID card, if I remember correctly.

Hope this helps,

Rob
