Solution

DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:(IS A SITE ENGINEER AVAILABLE?)

Field training in M10-4S servers

TASK COMPLEXITY: 4

Time Estimate: 30 minutes

FIELD ENGINEER INSTRUCTIONS

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY?: All the power cords must be disconnected to completely cut the power to the Crossbar box.

If there are any physical partitions (PPARs) in operation, the Crossbar Box cannot be powered off.

The Crossbar box must be completely shut down and depending on the type of maintenance either all PPARs, or a target PPAR must be shut down

1. If the target Crossbar box is the master XSCF then switch the Master role to Standby.

XSCF> switchscf -t Standby

2. Verify the physical partitions (PPARs) status with.

XSCF> showpcl -a -v

3. Powering off the affected PPARs will.

Shutdown logical domains.

Shutdown the control domains.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

Removing the Crossbar cable pair

Note Cables must be replaced in pairs

1. Follow maintenance steps for Inactive/cold maintenance or System-stopped maintenance

Inactive/cold maintenance

a. Verify that the PPAR that has the target M10-4s is powered off

XSCF> showpparstatus -p n where n is the PPAR that the M10-4s is used in

b. Execute the XSCF> replacefru BB#nn command to release the target M10-4s from the system

c. Remove all power cords from the Power Supply units of the target Crossbar box

Note - To completely shut down the system, all the power cords must be disconnected. There is a risk of electrical failure if the power cords are not disconnected.

System-stopped maintenance

a. Run XSCF> showpparstatus -a to verify that all the the PPARs connected to the Crossbar box are powered off.

b. Execute the XSCF> replacefru BB#nn command to release the target M10-4s from the system

Note - To completely shut down the system, all the power cords must be disconnected. There is a risk of electrical failure if the power cords are not disconnected.

Note - Before disconnecting the Crossbar cable pair be sure to take notes on the connection positions in order to reconnect the cables correctly.

2. Disconnect the Crossbar cable pair from SPARC M10-4S. Pull the tab on the cable to release it.

3. Disconnect the Crossbar cable pair from Crossbar box. Pull the tab on the cable to release it.

Installing the Crossbar cable pair

1. Reinstall the Crossbar cable pair to the SPARC M10-4S. This works best by connecting one cable at a time. Make sure the cables, click when you connect them.

2. Reinstall the Crossbar cable pair to the SPARC Crossbar box.

Note - Verify the cable connections with a XSCF> showlogs -V error after the Crossbar box is back in service

3. Connect all power cords to the power supply unit of the target Crossbar box.

Note - In a dual power feed, be sure to connect the power cord to the original position correctly according to the notes written down before maintenance.

4. Once the Crossbar box is up, return M10-4s to service by completing the XSCF> replacefru command.

5. Power on the target physical partition(s). This will depend on whether you powered down all the PPARs or just the target PPAR.

a.) Move the mode switches to locked on both the master and the standby cabinet.

b) Execute the switchscf -t Active command to switch the standby XSCF to the Master XSCF.

c.) Review the "showlogs -V error" output to confirm there are no cable errors.

OBTAIN CUSTOMER ACCEPTANCE

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

Verify the status of all domains.
