DISPATCH INSTRUCTIONS

WHAT SKILLS ARE REQUIRED?: No special skills required, Customer Replaceable Unit (CRU) procedure

TASK COMPLEXITY: 0

Time Estimate: 15 minutes

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY?:  The DISK can be replaced Active/Hot with some limitations or Inactive/Cold.

WHAT ACTIONS ARE REQUIRED?:

Enable DISK Unit for replacement ( Follow either the  Active/Hot or Inactive/Cold methods).

Active/Hot maintenance - NOTE: Boot disk devices can only be maintained with the Active/Hot method if they are redundantly configured with a RAID configuration.

HW RAID -

Operate only after checking the failed internal disk. See "12.2 Configuring Hardware RAID" in the SPARC M12 Systems System Operation and Administration Guide for details.

SW RAID -

For details, see the manual for the software in use.

NO SW or HW RAID Used -

1.  Display the Oracle Solaris super-user prompt (#).

2.  Execute the cfgadm (1M) command to check the status of the internal disk.

     # cfgadm -a

3.  Stop the applications from using the internal disk.

4.  Execute the cfgadm (1M) command to disconnect the internal disk to be maintained from the system.  (Ap_Id is from the cfgadm -a output from previous step).

     # cfgadm -c unconfigure Ap_Id

5.  Execute the cfgadm (1M) command to blink the CHECK LED of the internal disk to be maintained.

    # cfgadm -x led=fault,mode=blink Ap_Id

6.  Execute the cfgadm (1M) command to confirm that the internal disk to be maintained is disconnected - (The disconnected internal disk is displayed as "unconfigured").

     # cfgadm -a

7.  IF the internal disk to be maintained is in an "unconfigured" state ready to be removed see the Removing the internal DISK section below.

Inactive/Cold (System Stopped) maintenance

1.  Display the Oracle Solaris super-user prompt (#).

2.  Stop all guest domains - See "3.2.5 Shutting down logical domain" in the SPARC M10 Systems System Operation and Administration Guide for details.

3.  Stop the control domain - See "3.2.4 Powering off physical partitions individually" in the SPARC M12 Systems System Operation and Administration Guide for details.

4.  Switch the mode on the Operator Panel to service mode.

5.  Log into the XSCF.

6.  Stop the server using the poweroff -a command.  Verify the POWER LED is off, and disconnect the power cords. 

     XSCF> poweroff -a

Removing the internal DISK

1. Push the knob of the internal disk to release the lock and then open up the lever.
2. Hold the lever and pull out the internal disk 2 or 3 cm (0.8 or 1.2 in) to disconnect the internal drive from the backplane.
3. Carefully remove the internal disk from the slot and set on a conductive mat. - NOTE: If reducing the number if internal disks be sure to replace empty disk slot with filler unit.

Installing the internal DISK - NOTE: If expanding the number of internal disks be sure to remove the filler unit from the slot the new disk will be inserted into.

1. Open the lever of the disk and hold the disk.
2. Carefully insert the disk into the slot.
3. Close the lever and be sure the disk locks into place.

Reassembling the Server (Follow either the Active/Hot or Inactive/Cold methods).

Active/Hot maintenance

HW RAID -

Operate only after checking the failed internal disk. See "12.2 Configuring Hardware RAID" in the SPARC M12 Systems System Operation and Administration Guide for details.

SW RAID -

For details, see the manual for the software in use.

NO SW or HW RAID Used -

1.  Display the Oracle Solaris super-user prompt (#).

2.  Execute the cfgadm (1M) command to check the status of the installed internal disk and get the Ap_Id.

     # cfgadm -a

3.  Execute the cfgadm (1M) command to connect the internal disk to tha was just maintained to the system.  (Ap_Id is from the cfgadm -a output from previous step).

     # cfgadm -c configure Ap_Id

4.  Execute the cfgadm (1M) command to confirm that the internal disk just installed is now connected - (The installed internal disk should now be displayed as "configured").

     # cfgadm -a

5.  IF the internal disk just installed is now in a "configured" state then disk is now available for applications.

Inactive/Cold (System Stopped) maintenance

1. Connect all the power cords to power outlets.
2. Verify that the XSCF STANDBY LED on the operator panel is on.
3. Turn the mode switch on the operator panel to the locked mode position.
4. Log into the XSCF.
5. Confirm hardware fix by running the following commands:

          XSCF> testsb -y -p 00-0 (This will test the system boards and backplane by running probe-scsi-all to verify the disks are seen and display the results).

  XSCF> showstatus

  XSCF> showhardconf

  XSCF> poweron -a

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION NEED TO TAKEN TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:

Due to Bug 17451091 in Solaris 10 and Bug 15606570 in Solaris 11 FMA disk errors may not be cleared when the disk is replaced. This will result in replay errors.

Once the disk has been replaced check FMA to make sure the error was cleared:

# > fmadm faulty

If the disk is still showing in error, then clear the error by doing:

# > fmadm acquit <UUID>
