Enable and Verify a DIMM
Enable and Verify a DIMM
1.
Use the show faulty command to determine how to clear the fault.
■ If the output indicates a POST-detected fault, go to Broken Link (Target ID:
Z40006B61395820).
■ If the output displays a UUID, which indicates a host-detected fault, skip
Broken Link (Target ID: Z40006B61395820) and go directly to Broken Link
(Target ID: Z40006B61390176).
2.
Use the set command to enable the DIMM that was disabled by POST.
In most cases, replacement of a faulty DIMM is detected when the SPM is power cycled. In
those cases, the fault is automatically cleared from the server. If show faulty still displays the
fault, the set command clears it.
-> set /SYS/MB/CM0/CMP/MR0/BOB1/CH0/DIMM clear_fault_action=true
Are you sure you want to clear /SYS/MB/CM0/CMP/MR0/BOB1/CH0/DIMM (y/n)? y
Set 'clear_fault_action' to ‘true’
3.
For a host-detected fault, perform the following steps to verify the new DIMM.
a.
Set the virtual keyswitch to diag so that POST runs in Service mode.
-> set /HOST keyswitch_state=Diag
Set 'keyswitch_state' to 'Diag'
b.
Stop the host.
-> stop /System
Are you sure you want to stop /System (y/n)? y
Stopping /System
c.
Check if the host has been powered off.
Allow approximately one minute before performing this step. Type the show /HOST
command. When the host is powered off, the console displays status=Powered Off.
d.
Start the host.
-> start /System
Are you sure you want to start /System (y/n)? y
Starting /System
