1849.0. "Questions about SWXCR-04" by NETRIX::"hancock@alf.dec.com" (Steve Hancock) Wed Jan 29 1997 15:27

Hi folks,

I have a customer with an ASE configuration as follows:

2 - 1000A, 256 MB, 4.7 FW
2 - KZPSA, P01 A10 FW
1 - SWXRC-04 - v2.7 FW
10 - RZ29B's mirrored

UNIX 4.0b
ASE 1.4

When he boots the second system in the ASE, he gets:

 "pkb0.1.0.13.0 bad scsi status 18
  file open failed for dkb100.1.0.13.0"

This is prior to the OS starting to load from the console. The
systems appear to operate fine in any case. 


I have the following questions:

1) Is the SWXCR-04 supported for ASE/TCR? I checked the SPD and 
its not there.

2) What does this message mean? Is it coming form the firmware? 
Should we be concerned?


Regards,

1849.1Should be SWXRC-04NETRIX::"hancock@alf.dec.com"Steve HancockWed Jan 29 1997 15:456
My mistake. Should be SWXRC-04.

A swxcr can only be used for private storage on a system.

So the base os supports it, but it is not support as a cluster shared
device.

I think you should discuss with hardware or storage what the error
you are seeing is...I don't know off hand.

Hi

 If the swxxxx is an HSZ, it should be supported as a shared device...

So is this an HSZ40 or a PCI Raid controller?


1849.4That's what I want to know.NETRIX::"hancock@alf.dec.com"Steve HancockThu Jan 30 1997 12:0812
That's the question I am asking. I know that an HSZ40 and HSZ50
are supported per the ASE 1.4 SPD. What I need to know is from
engineering's perspective, is a SWXRC-04 the same thing as an
HSZ40 since it runs the same firmware or not? If it is the same,
is it supported? And, has anyone seen the error in .0?

Hi

 I think the scsi id string (seen during boot, or via
scu show edt) is hsz40 or hsz50, you are all set...


1849.6SWXCR-04 != HSZ40 (but it's close)SMURF::KNIGHTFred KnightFri Jan 31 1997 15:3518
NO, the SWXCR-04 is NOT supported.  Neither in the base nor in ASE/TCR.

It is basically an HSZ40, but the S/W doesn't know that, so none of our
HSZ40 specific code gets used.  If you want a supported HSZ40 then get
a HSZ40.  If you want it to work (but continue to be unsupported) then
you must add device recognition.  Without recognition you will get some
unexpected stuff happening (particularly around error events).

To add recognition, duplicate the HSZ40 entry, and change the name to
match what the SWXCR-04 returns for it's inquiry data.

This was not an oversight.  The CXO product management specifically
made the decision to NOT support the SWXCR-04 on Digital UNIX.  They
wanted support ONLY for the HSZ family.  The SWXCR-04 was for the
off-base market, NOT for the on-base customers.  We just did what
the H/W product management people told us to.
