Procedure for replacing the J4400 Chassis connected to a Sun ZFS Storage 7000 Series NAS

Solution

 
WHAT SKILLS DOES THE ENGINEER NEED: Product Knowledge, Sun ZFS Storage 7000 [C].

TIME ESTIMATE: 150 minutes

TASK COMPLEXITY: 1

PROBLEM OVERVIEW
What: Need to replace a J4400 chassis connected to Sun ZFS Storage 7000 [C] .
Where: Chassis ID:  Chassis S/N: :  (to be inserted by TSC)
Why : Faulty chassis replacement required as determined by TSC.
 

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

The system should be powered off.

## WARNING ##

This procedure requires shell level commands to be run during Step 9. These can only be performed by Oracle trained engineers. 

If the field is attending site they should contact the TSC engineer responsible for this action plan to gather the required information before attending site.

If this replacement is to be performed by the customer, please ensure Oracle TSC is engaged and scheduled in advance to perform these steps remotely via Oracle shared shell.

###########

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

1) Back up all data stored on the array.( This should taken care by customer prior to scheduling the activity)
 
2) Stop all system I/O to the array.
   Verify that the failed chassis is ready to be removed.and take ESD precautions.

3) Cluster failover through power-off one node

   -head-1>maintenance
   -head-1:maintenance> system
   -head-1:maintenance system> poweroff
   
   This will turn off power to the appliance. Are you sure? (Y/N) Y
 
4) Unconfig Pool on a live node
   
   -Configuration->STORAGE" screen in the BUI
   -Select pool and press "UNCONFIG"
 
5)  Power-off the live node
     
      -head-2>maintenance
      -head-2:maintenance> system
      -head-2:maintenance system> poweroff
   
   This will turn off power to the appliance. Are you sure? (Y/N) Y
 
6) Physical swap the chassis
 
 i) Removing a Chassis
 
  -Disconnect the power cord from each power supply
  -Label each mini-SAS cable connection for reconnection to the same connectors on the replacement chassis
  -Disconnect the labeled mini-SAS cables from each SIM board
  -Remove each SIM board from the chassis
  -From the front of the cabinet, remove each disk drive and disk filler assembly
  -After you have removed all of the components from the chassis, remove the chassis from the cabinet
 
 ii) Installing the New Chassis
 
   - From the front of the cabinet, slide the new chassis into the cabinet until the front flanges of the chassis touch the vertical face of the cabinet
   - Tighten the captive screws on each side of the tray front to secure the chassis to the cabinet.
   - At the back of the cabinet, slide a system locking clip onto each lower corner of the chassis. You can use a Phillips head screwdriver for leverage to help you push in the clip
   
  iii) Installing CRUs Into a New Chassis
 
    -From the front of the cabinet, install each disk drive and disk filler assembly into. For each disk drive and disk filler assembly
    -From the back of the cabinet, install the two SIM boards in the SIM slots
    -Install the two power supplies into the chassis slots
    
   iv) Completing the Chassis Installation
   
    -From the back of the cabinet, reconnect the country-specific power cables into each of the power supply connectors.
    -Replace the power cord tie strap on each power cord.
    -Turn on power to both power supplies.
    -Check the status of the tray.
    
7)  After Power-on the JBOD and power-on single head.
   -> JBOD and head-1 Node PowerOn
 
   - Power up JBODs first
   - Power on head by pressing small button the front left hand side or using "start /SYS" from the SP.
    
    
8)  Import Pool on the live node
   ->  Import pools using the "Configuration->STORAGE" screen in the BUI
 
 
9) At this stage Oracle will need to run a shell level command to update the new chassis serial no. This should only be done by a trained Oracle Engineer.

    This can be done by either -

      i)  Oracle NAS TSC team - Please ensure you have previously scheduled / engaged Oracle TSC to join a shared shell to run this procedure.

      ii) Oracle Field team - The field team should have gathered the procedure from TSC engineer before attending site.

    
10) Reassign pool ownership for the normal cluster environment

11) Power on the remain node

12) Failback resources

13) Check the chassis serial number.

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:

Confirm appliance is in normal state and the client data access, pool is online and no faults (related to disks) reported in BUI.

Mark Repaired any prior related disk faults.

Deactivate locator LED on the new drive via BUI/CLI.
