How to remove and replace a Starcat System Control Peripheral Board SCSI Cable

Solution

CAP PROBLEM OVERVIEW: System Controller Peripheral Board SCSI Cable Failure

DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:

Starcat Traning

TASK COMPLEXITY: 4

TIME ESTIMATE: 180 minutes

DELIVERY REQUIREMENT:

Immediate

FIELD ENGINEER INSTRUCTIONS

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? N/A

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

If the affected SCper is the spare goto "Shutdown Spare SC"

1. Powering Off a System Control (SC) Board
• If this is the main SC ensure the spare SC is available.
• Sync the main to the spare
  
  sc% setdatasync backup
  If no messages are reported in /var/opt/SUNWSMS/adm/platform/messages and the command completes, the setdatasync backup was successful.
• As a superuser on the main SC, make a backup copy of the SMS configuration:
  
  sc# smsbackup directory
• From the main SC, failover (switch over) to the spare SC by typing:
  sc% setfailover force
• On the main SC, verify that it has assumed the main role and that failover is disabled by typing:
  
  sc% showfailover -r
  MAIN
  sc% showfailover
  SC Failover Status: DISABLED
• On the main SC, disable the failover mechanism by typing:
  
  sc% setfailover off
• Verify the failover is DISABLED by typing:
  
  sc% showfailover
  SC Failover Status: DISABLED
  
  
  Note: Before shutting down and replacing an SC make sure that clock from the other SC to all components is in a good state. To check this run "showboards -c" command for SMS 1.4 and later. ( See Document ID: *1006413.1- Check clock status before replacement of System controller*for more information )
• Shutdown the spare sc:
  
  sc_spare# shutdown -y -g seconds -i 0
• Power off the spare (inactive) SC from the main SC by typing the following SMS command:
  
  sc% poweroff scx
2. Remove the SC Peripheral Board
3. Remove the SCSI Cable
• At the center SCSI access panel, remove the four M3x6 flathead screws and remove the access panel.
• Disconnect and replace the SCSI ribbon cable connector.
4. Install the center SCSI access panel and secure with the four M3x6 flathead screws.
• Remove the connector protective cover from the board being installed and inspect the connector for any damaged or gaps between the pins.
• Ensure board alignment tabs are not bent.
• Inspect the mating connector before inserting the new board.
5. Install SC Peripheral Board
6. Power on SC Peripheral Board. ( From the main SC type: )
   
   sc% resetsc
7. Verify System Control (SC) Peripheral Board
• Monitor SCPOST for any error messages during SC boot. SCPOST messages are output to an SMS console. To read SC SMS console messages, you must attach a console cable and terminal to the SC.
• Ensure that Solaris software can communicate to all the peripheral devices.
  
  • For the DVD-ROM, insert a CD and ensure it mounts properly.
  • For hard disks, check that the /dev/dsk and /dev/rdsk entries are correct and that the Solaris software can access the disks (format, prtvtoc).
  • For the DAT drive, check that the /dev/rmt entries are correct and that the Solaris software can access the tape device (mt status).
