Dear Managers,

I am, at present quite confused by a problem on an AlphaServer 8200 system
running Digital UNIX 4.0D and TruCluster ASE version 1.5. The system is
configured with 2 GB of memory and shares 160 GB of RAID 0+1 disk storage in a
RAID Array 7000 with with another AlphaServer 8200. The problem I am getting is
that recently the node "sampson" has started making a large series of errorlog
entries. The output of uerf from this looks like the following.


********************************* ENTRY 1. *********************************

-----------------------------------------------------------------------------------

It seems that a similar error entry gets logged approximately every second and
they seem to all be singling out the devices at [SCSI Bus#, Target, Lun]

[8,1,1], [8,1,2], [8,2,0], [8,3,0], [8,3,1], [8,2,1], [8,1,1] and so on for each
of the devices attached to that bus.

I was wondering if anyone could tell me what this kind of error entry means.
What is the cdisk_op_spin routine? Should I be alarmed?

Yours sincerely,
Robert Honore.
