problem configuring fibre channels

Hi all,

 

I got an RX4640 running OpenVMS8.4 (booted as sateliet from an RX2600) and a DS2400 equiped with 15 FC-disks. Both are connected to a BROCADE Silworm 3200 switch, but on the RX4640 I see none of the disk-devices. On the switch I see both the DS2400 (port0) and the RX4640 (port1):

 

beer:admin> switchshow
switchName:    beer
switchType:    16.2
switchState:    Online   
switchMode:    Native
switchRole:    Principal
switchDomain:    1
switchId:    fffc01
switchWwn:    10:00:00:60:69:c0:88:92
switchBeacon:    OFF
Zoning:          OFF
port  0: id N1 Online         L-Port 15 public, 1 private, 2 phantom
port  1: id N2 Online         F-Port 21:00:00:e0:8b:02:04:9d
port  2: -- N2 No_Module      
port  3: -- N2 No_Module      
port  4: -- N2 No_Module      
port  5: -- N2 No_Module      
port  6: -- N2 No_Module      
port  7: -- N2 No_Module      

 

and I see devices:

 

beer:admin> nsallshow 8
{
  01109b 01109d 01109e 01109f 0110a3 0110a5 0110a6 0110a7
  0110a9 0110aa 0110ab 0110ac 0110ad 0110ae 0110b1 0110b2
  011100
17 FCP Ports }


 

 

On my RX4640 the FC card seems normal:

$ sh dev/full fg

Device FGA0:, device type QLogic ISP23xx FibreChannel, is online, shareable,
    error logging is enabled.

    Error count                    0    Operations completed                292
    Owner process                 ""    Owner UIC                      [SYSTEM]
    Owner process ID        00000000    Dev Prot              S:RWPL,O:RWPL,G,W
    Reference count                0    Default buffer size                   0
    Current preferred CPU Id       1    Fastpath                              1
    Current Interrupt CPU Id       1
    FC Port Name 2100-00E0-8B02-049D    FC Node Name        2100-00E0-8B02-049D

 

However I do not "see" any of the disks of the DS2400 on the RX4640. So I tried:

$ mc sysman
SYSMAN> SET ENVIRONMENT/CLUSTER
%SYSMAN-I-ENV, current command environment:
        Clusterwide on local cluster
        Username SYSTEM       will be used on nonlocal nodes

SYSMAN> IO FIND_WWID

%SYSMAN-I-OUTPUT, command execution on node BOLERO
No previously undiscovered WWIDs have been found.


%SYSMAN-I-OUTPUT, command execution on node VALETA
No previously undiscovered WWIDs have been found.



This does not seem to help. What do I overlook/do wrong?

Re: problem configuring fibre channels

I have a different environment, but one point is important:

 

the switch must assign a unit identifier and this identifier is used by OpenVMS as the LUN:

 

MSA> show unit 0

Unit 0:
In PDLA mode, Unit 0 is Lun 1.
Unit Identifier: 1001
HSG Unit Identifier: 1001
Device Identifier: 01000010:6001-4380-0006-3C90-0B2E-BAB8-08DC-004C
Cache status      : enabled
Max Boot Partition: Unknown
Volume status     : VOLUME OK
 4 Data Disk(s) used by lun 1:
   Disk 0: Partition 0; (SCSI bus 0, SCSI id 0)
   Disk 1: Partition 0; (SCSI bus 0, SCSI id 1)
   Disk 2: Partition 0; (SCSI bus 0, SCSI id 2)
   Disk 3: Partition 0; (SCSI bus 0, SCSI id 3)
Spare physical drives:
   No spare drives are designated.
Logical Volume Raid Level: RAID 5. Distributed Data Guard
                           stripe_size=64.0KB
Logical Volume Capacity : 101.75 [109.26] GB

OpenVMS recognizes this unit as "$1$dga1001".

Re: problem configuring fibre channels

MSA only gives me information for the SCSI controler used for some other disks, but no info on the FGA0 device

 

However I managed to see the disks on the OpenVMS system:

How should I proceed? Can I use the WWID's to configure the device so that OpenVMS recognizes it as a (disk)device?

Re: problem configuring fibre channels

No, the WWID does not help.

 

The switch must assign a identifier to the unit.

 

The controller needs a identifier, too, in order to be recognized by OpenVMS.

Re: problem configuring fibre channels

I get lost....

 

What identifier should the switch generate? I thought the WWID's defined the adresses at the switch.

 

 

Why does not my FG-controller gets an ID? Is this because no disks are assigned to it (I cannot use the A&B SCSI in MDA either, only the C-SCSI which has disks attached)

Re: problem configuring fibre channels

Pretty much everything within a FC SAN has an id assigned to it; these are akin to the MAC addresses used on an Ethernet network.  Here are some of the baseline console-level FC SAN commands and OpenVMS-level FC SAN commands that can be involved with the configuration process.

Re: problem configuring fibre channels

Sorry Hoff , I already located those documents but they do not help me further:

 $   @SYS$MANAGER:BOOT_OPTIONS.COM

does not list the devices either (nor anything in the efi-shell)

The file SYS$SYSTEM:SYS$DEVICES.DAT does not exists so no WWID's are found. The only command on the VMS side that let me know the devices are present is

$ MCR SYS$ETC:FIBRE_SCAN
which gives Portnumber and Nodename (actually the same I see on the switch. But they seem to be something else than the WWID OpenVMS seems to like. I have no idea how to generate this last ID.

Re: problem configuring fibre channels

Do you have a supported FC HBA installed?  It would seem not.  (Or you have device autoconfiguration disabled.)

Re: problem configuring fibre channels

probably not supported. but not supported does not always mean not working.

 

It is a "standard" install of OpenVMS so I assume that autoconfiguration is on (otherwise I do not think "served-cluster-disks" are recognized.

Isd there a way to "manusally" configure the disks?

Re: problem configuring fibre channels

Jouk,

 

is the DS2400 supported as a SAN storage array for OpenVMS ?

 

The data from FIBRE_SCAN seems to indicate, that OpenVMS can reach die DS2400, but cannot configure the disks on that storage box. Do you have a manual for that DS2400 ?

 

Volker.
