Network Status
The network status information that displays depends on whether Network Fault Tolerance is enabled. When Network Fault Tolerance is enabled, Ethernet port 1 automatically takes over network communications if Ethernet port 0 fails. If Network Fault Tolerance is enabled, network status information displays for the network ports Ethernet 0, Ethernet 1, and Bond 0. If Network Fault Tolerance is not enabled, status information displays only for Ethernet 0.
To view the network status, follow this procedure:
Procedure
Step 1 From the Cisco Unified Communications Operating System Administration window, navigate to Show > Network.
The Network Settings window displays.
Step 2 See Table 3-2 for descriptions of the fields on the Network Settings window.

Rebuilding RAID Drives
A RAID drive may fail and may require manual intervention to rebuild one of the physical drives in a logical pair during normal operation.
RAIDed disks, also termed RAID arrays, get arranged in logical pairs. A single logical pair comprises two physical drives. The system keeps the pair of drives in sync with the same data in real time to provide redundancy ultimately for data integrity and assurance. When one physical drive fails to synchronize or begins to experience read or write failures, you may need to rebuild the drive. Many things can cause the failure, but the main concern remains whether the data in a logical drive pair is compromised due to failures in one of the physical drives.
Monitoring software usually detects RAID failures, and failures get reported as a failed drive or a loss of drive redundancy. The procedure for rebuilding a failing drive follows and applies to all Cisco MCS model 7825, 7835, and 7845 servers.
First, check the status of the RAID array by using the CLI show hardware command and verify whether the Status field reads Ok or Okay. An example follows:
Type : Intel(R) Xeon(TM) CPU 3.06GHz
Object ID : 1.3.6.1.4.1.9.1.585
OS Version : UCOS 2.0.1.0-37
Found 1 IBM ServeRAID controller(s).
Read configuration has been initiated for controller 1...
----------------------------------------------------------------------
Logical drive information
----------------------------------------------------------------------
Status of logical drive : Okay (OKAY)
Write cache status : Temporary write through (TWT)
Array A stripe order (Channel/SCSI ID) : 1,0 1,1 Command completed successfully.
If the RAID array status field does not read Ok or Okay (for example, shows Degraded or Critical), perform the following steps:
Step 1 Log in to console and enter the CLI command, utils system shutdown.
Step 2 Power off the server (press power off button).
Step 3 Extract the failed disk drive.
Step 4 Power up the server (press power on button).
If the server is an IBM server (for example, a 7825I, 7835I, or 7845I), the following menu will appear during system reboot:
1:ServeRAID-5i Slot 2, Logical drv=1, Firmware=7.12.07, Status=Fail
1 Drive(s) not responding or found at new location(s)
Press F2 Detailed information
F5 Change the configuration and set the drive(s) defunct
F10 Continue without changing the configuration
Step 5 Press F5
Step 6 After the login prompt appears in the console window, log in and check the status of the RAID array by using the CLI show hardware command; the Status field should read Degraded or Critical.
Step 7 Insert the failed disk drive into the original slot; be sure to lock it properly in place.
Step 8 Check the status of the RAID array by using the CLI show hardware command; the Status field will read Rebuilding or Critical.
Step 9 After an hour, recheck the status of the RAID array by using the CLI show hardware command and verify that the Status field reads OK or Okay.
If the status does not read OK or Okay, you may need to replace the physical drive.
