638.0. "Warning! cannot attach scsiport1 ... Error..." by MDR01::MONJE (MCS Madrid) Wed Feb 19 1997 11:02

    Hi,
    
    2 AlphaServers 2000 5/300.  128 MB Phy. Mem
    				Windows-NT 4.0 SP#2
    				Digital Clusters Windows NT beta 1.1
    
    				SCSI-0 --> 2 rz29 disks
    					   boot/system and applic disks
    						NT C: drive
    						NT D: drive
    						NT E: drive
    
    
    				SCSI-1 --> KZPSA
    					   Raid Array 450 cabinet:
    						2 HSZ50
    					   	6 rz28 disks
    					  	 Raid-5 : 
    						    3 disks --> NT F: drive
    						    3 disks --> NT G: drive
    	
    
    Installed new drivers for KZPS (v3.01), included in a subdirectory of
    the beta v1.1 Digital Winnt Clusters.
    
    Installed beta v1.1 at the two AlphaServers 2000 5/300. All seems to be
    Ok.
    
    Problem is when I reboot the 2 AlphaServers 2000 and they try to attach
    the scsi port 1 (KZPSA). I start the first server without any problem
    and I logont to NT and check that Cluster services are up and running.
    Next, I start second server, when it load kernel and load the cluster
    driver gives a Warning message:
    
    Warning! cluster cannot attach ScsiPort1  ! (don't know the problem)
    
    I do a logon to this second server and check the Cluster services, all
    are up and running. When I run the cluster config. utility it gives an
    error messagess about the DLL disk driver, and tells me to check log
    files and abort config. utility. Checking log files, I see that Cluport
    cannot to attach the scsi port 1. I can't do anything from this Cluster
    member.
    
    Any ideas about why this warning error ??
    
    I did some tests: 
    
    If I turnoff the raid cabinet, and start one server it loads the
    cluster driver after loads the kernel without problems (evidently I
    can't availables rRAID disks). Next I start second server, it loads
    kernel and cluster driver without errors.   If cabinet is turn-on  with
    RAID disks availables, the first server started load cluster SW and
    attachs the scsiport1. Always the second server (each of the two
    servers) started, doesn`t load cluster driver and give the error: 
    
    Warning! cluster cannot attach ScsiPort1
    
    
    Inputs please ?
    
    Help would be best appreciated.

The cluster software is telling you that the Raid configuration,
hardware, or kzpsa (firmware perhaps) is not working as expected.
Think of the cluport error as the messenger of this problem. 
 Look at the SCSI device map for clues.  My first guess would be the
450 is not configured correctly for clusters. Check Host functionality,
termination ect. ect.

    You give me the correct way. Problem was in the HZS50's. 
    From the HSZ50 console you need to redefine a specific parameter called
    "host_function".
    
    Host_function parameter has 4 possible values:
    
    host_function = A   ! That means host is a VMS, Digital Unix, Sun 
    host_function = B   ! That means host is a IBM
    host_function = C   ! That means host is a HSZ15 emulation
    host_function = D   ! That means host is Windows NT 
    
    By default its value is A (VMS, Digital Unix, Sun).
    
    The answer to my problem is put the host_function value to D
    
    HSZ50> SET THIS HOST_FUNCTION = (0,D)
    HSZ50> SET THIS HOST_FUNCTION = (1,D)
    HSZ50> SET THIS HOST_FUNCTION = (2,D)
    HSZ50> SET THIS HOST_FUNCTION = (3,D)
    HSZ50> RESTART THIS
    
    If you have a second HSZ50 you need to do the same command but
    different syntax:
    
    HSZ50> SET OTHER HOST_FUNCTION = (0,D)
    		:
    		:
    HSZ50> RESTART OTHER
    
    But if second HSZ50 is working as backup of first HSZ50 you don't need
    to do this second command (HSZ50> SET OTHER HOST_FUNCTION = (0,D) )
    because the HOST_FUNCTION is updated at same the time in the two
    HSZ50's.
    
    
    Now, it works fine  !!
    
    ThanKs and regards
