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:
valeta-sys) MCR SYS$ETC:FIBRE_SCAN

End of scan for port FGA.
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.
