The Solution:
the HSZ40 didnīt identify the error. I saw all the logs, the FMU (Fault,
Manager Utility ), UERF, and i spoke with DEC hardware and software
support but we only had a message of a hardware error in the logical
device and nobody could explain why the cluster didnīt assign (flashing
the error led)the dammage device.
The hszterm 'show disks' ,'show failedsets' and all the others commands
didnīt show any problem.
So the only way to find the phisycal device error was using the DECevent
software ( command : dia -t s:25-sep-1997:08:00:00
e:25-sep-1997:14:00:00 ):

------- HSZ Data -------
Instance Code x0252000A The last block of data returned
contains a
forced error. A forced error occurs
when a
disk block is successfully
reassigned,
but the data in that block is lost.
Re-writing the disk block will
clear the
forced error condition. The Device

So in hszterm i did : locate ptl 3 0 0 , and so i had my rz29b xxthe
DEC changed my RZ29B disk.
