Connecting an MQuad to an EMC Symmetrix

This section describes connecting an EMC Symmetrix to a NUMA-Q 1000 MQuad running Windows NT through a Fibre Channel Arbitrated Loop. Troubleshooting information is also included.


Director Flags on the EMC Symmetrix


ATTENTION

All configuration settings on the EMC Symmetrix must be carried out by EMC personnel.


For Windows NT, the EMC director flags must be set differently than with DYNIX/ptx. The following director flags must be set to on for the FC ports connecting to an MQuad running Windows NT: T, C, A, UWN, H, Loop ID. The D bit is only needed when clustering is being used.


Installing the FC Host Adapter

These are the steps to install a V4 FC host adapter (Emulex SuperFly 7000e) with miniport drive in an MQuad:

  1. Power down the desired MQuad.

  2. Install the FC host adapter in an open slot.

  3. Boot Windows NT.

  4. Open the SCSI Adapters window from the Control Panel.

  5. Open the Drivers tab, click on Add, then click on Have Disk.

  6. Enter the path to the driver for the SuperFly 7000e (Oemsetup.inf). The most current driver is 4.20SLI-2 and can be downloaded from the following FTP site:

    ftp://ftp.emulex.com/pub/fibre/lp7xxx/lp7driver/nt/scsi/4.20SLI-2
    
  7. Reboot the MQuad.

If the Symmetrix has drives configured to its FC ports (the ports that are connected to the MQuad), and the FC optical cable is connected, the MQuad should start seeing drives on the Symmetrix after reboot.


Making Dual-FC Connections to EMC Symmetrix

Normally, if you configure two FC host adapters to connect to the same set of Symmetrix drives (that is, if you set up redundant connections), Windows NT views the drives as two independent sets. You can remedy this condition by running a utility from EMC called PowerPath. This software tells Windows NT that the two boards are a dual-connection to the same disks. Currently there has been only minor testing with this utility.


Troubleshooting

If Windows NT does not see any drives on the Symmetrix, check the back of the FC host adapter board. The green light should be on and steady and the yellow light should be flashing. If the yellow light is not flashing, or if the green light is blinking, check the following conditions:

If the problem persists, check the driver. On the console screen, open SCSI Adapters from the Control Panel. Click on the Drivers tab. You should see the following entry:

Emulex LP6000/LP7000/LP8000LP850, PCI-Fiber...(Started)

If the word "Started" does not appear, the driver has not started. If the driver has not started, go to the Readme.txt file that comes with the driver zip file from Emulex and read the section "MICROSOFT NT ISSUES/INFORMATION."

If the problem persists, and you have checked the following conditions:

contact the EMC Symmetrix administrator to ensure that the Symmetrix ports are configured correctly.

If after all these steps the MQuad still does not recognize drives in the Symmetrix, you may have a defective host adapter board.
