6.
At the LOADER prompt, confirm the date and time on the replacement node:
show date
The date and time are given in GMT.
Step 2: Verify and set the HA state of the controller module
You must verify the
HA state of the controller module and, if necessary, update the state to match your system
configuration.
1. In Maintenance mode from the replacement controller module, verify that all components display the same
HA state: ha-config show
If your system is in… The HA state for all components should be…
An HA pair ha
A MetroCluster FC configuration
with four or more nodes
mcc
A MetroCluster IP configuration mccip
2.
If the displayed system state of the controller module does not match your system configuration, set the
HA
state for the controller module: ha-config modify controller ha-state
3.
If the displayed system state of the chassis does not match your system configuration, set the
HA state for
the chassis:
ha-config modify chassis ha-state
Step 3: Run system-level diagnostics
You should run comprehensive or focused diagnostic tests for specific components and
subsystems whenever you replace the controller.
All commands in the diagnostic procedures are issued from the node where the component is being replaced.
1.
If the node to be serviced is not at the LOADER prompt, reboot the node:
halt
After you issue the command, you should wait until the system stops at the LOADER prompt.
2. At the LOADER prompt, access the special drivers specifically designed for system-level diagnostics to
function properly:
boot_diags
During the boot process, you can safely respond y to the prompts until the Maintenance mode prompt (*>)
appears.
3.
Display and note the available devices on the controller module:
sldiag device show -dev mb
The controller module devices and ports displayed can be any one or more of the following:
◦ bootmedia is the system booting device.
◦ cna is a Converged Network Adapter or interface not connected to a network or storage device.
◦ fcal is a Fibre Channel-Arbitrated Loop device not connected to a Fibre Channel network.
