Disk Drive Enclosure Connection
To obtain the WWNs of the FCSA, you must download the firmware. To download the
firmware:
1. Use SCF to add the DISK object
2. Then start the DISK object (the DISK object does not have to come up).
3. After the firmware has been downloaded, determine the FCSA WWNs by:
a. Issuing the STATUS ADAPTER, DETAIL or STATUS ADAPTER, SACS
command.
b. Examining the Port Name and Node Name fields in the resulting display. The
contents of these fields contains the WWNs.
c. You can provide the WWNs to the ESS and FC switch administrators.
An FCSA can be installed without shutting down the system.
Disk Drive Enclosure Connection
Any connection between a NonStop S-series system or an Integrity NonStop NS-
series system and a disk drive enclosure containing M8xxx fibre channel disks requires
the services of two processes: the Fibre Channel Storage (FCS) Manager, which is
part of the Storage Manager ($ZZSTO), and the FCS Monitor $FCSMON), a persistent
generic process that runs in all processors.
Before connecting a disk drive enclosure to an FCSA, make sure that an FCS Monitor
process is running in all processors. Each of the two SACs on an FCSA can support as
many as four disk drive enclosures, for a total of eight per FCSA. The FCS Manager
process assigns a SAC on an FCSA to a particular instance of the FCS Monitor.
The FCS Monitor process performs these tasks:
•
Accepts requests from FCS Manager process.
•
Provides the FCS Manager with information about disk drive enclosure information.
•
Notifies Configuration Services (ZCNF) of hardware changes in disk drive
enclosures and in the process updates the PCT.
•
Generates Hardware Change events to Service logs ($ZLOG).
•
Generates Environment status change events to Service logs ($ZLOG).
•
Polls the EMU of every disk drive enclosure being monitored.
•
Issues control commands; for example, disk location LED indicator ON/OFF to an
EMU.
•
Issues FIR information request commands like hardware type and revision to an
EMU.
•
Issues FCDM Enclosure status commands to EMU.
