To access the HP Smart Array CLI commands on ESXi:

1. In the VMware Host Client, select Host > Manage > Services.
   The following window is displayed.
   
2. Start the TSM-SSH service.
3. Using an SSH tool such as PuTTY, log on to the ESXi host.
   
4. Enter the user and password that you used to access VMware Host Client.
5. Enter the command, using the following format:
   esxcli ssacli cmd --cmdopts="commandToRun"
   where commandToRun is one of the following:
   ctrl all show config – Show configuration.
   ctrl all show status – Controller status.
   ctrl all show detail – Show detailed controller information for all controllers.
   ctrl slot=0 show detail – Show detailed controller information for controller in slot 0.
   ctrl slot=0 pd all show status – Physical disk status.
   ctrl slot=0 pd all show detail – show detailed physical disk information.
   ctrl slot=0 ld all show status – Logical disk status.
   ctrl slot=0 ld 2 show – View detailed logical disk status.
   ctrl all diag file=filePathAndName – Output diagnostic information about the controller in slot 0 as a zip file to a file, where filePathAndName is the output file path and name.
   ctrl slot=0 diag file=filePathAndName – Output diagnostic information about all controllers as a zip file to a file, where filePathAndName is the output file path and name.
   ctrl slot=0 ld 2 modify led=on – Turn on Blink Physical Disk LED.
   ctrl slot=0 ld 2 modify led=off – Turn off Blink Physical Disk LED.
   For example, to display the configuration, use the following command: esxcli ssacli cmd --cmdopts="ctrl all show config".
6. Stop the TSM-SSH service.
   CTERA recommends keeping SSH disabled.

Using HPE Integrated Lights Out (iLO)

HPE iLO enables remote HC1200 CTERA Edge Filer monitoring seamlessly from anywhere in the world. The first time you log on to iLO, CTERA recommends changing the password.

To Access iLO:

• Attach a network cable to the iLO port.

To change the password to access iLO:

1. Log in to iLO.
   
2. Use Administrator as the user name and CTERAiLO4 for the password.
   The iLO console is displayed.
   
3. In the iLO console, access Administration > User Administration.
   
4. Click Administrator under Local Users.
   
5. Check the Change Password box and click Update User.
6. Enter a new password and then confirm it.

Using iLO, you can monitor the sever, including the following:

• Set up SNMP monitoring under Administration > Management > SNMP Settings. For more details, see http://www.youtube.com/watch?v=x8lP3tjcNqk or for SNMPv3, http://www.youtube.com/watch?v=eSyk1pX8TZ8. You can also set up SNMP monitoring of the CTERA Edge Filer, described in Using SNMP Monitoring.
• Set up email alerts under Administration > Management > Alert Mail. For more details, see http://www.youtube.com/watch?v=N_gZ5eFZws4.
• System information. Click System Information in the navigation pane to view the status of the server subsystems and devices, such as the status of the fans, power, storage, and temperature. For example, by selecting the Storage tab, you can check the status of all the SATA drives.
• System diagnostics. Click Diagnostics in the navigation pane for server diagnostics.

Enabling Support For Link Failover

The HC1200 CTERA Edge Filer has two 10GbE Ethernet ports. You can use both these ports to enable link failover, whereby if one interface fails, the server reestablishes a link to the network using the other interface. This is configured by configuring NIC Teaming in ESXi.

To enable link failover:

1. Connect Ethernet, or fiber, cables to both the 10GbE Ethernet ports, or fiber ports, at the back of the HC1200.
2. Log in to the VMware Host Client, as described in Monitoring the CTERA Edge Filer From the VMware Host Client.
3. In the VMware Host Client, select Networking in the Navigator and select the CTERA 10GbE virtual switch.
   The Edit standard virtual switch window is displayed.
4. Click Add uplink and enter a name for the new uplink and choose the option for the link.
5. Expand NIC teaming and make sure Load balancing is set to Route based on originating port ID.
   Load balancing – set to Route based on the originating port ID.
   Network failover detection – set to Link status only.
   Notify switches – set to No.
   Failback – set to Yes.
   Failover order – Leave the default.
6. Click Save.

If a physical network cable is disconnected access to the CTERA Edge Filer continues transparently as all SMB connections and the browser user interface remain connected.

Running Additional Applications

Each H Series CTERA Edge Filer includes an ESXi hypervisor. This hypervisor has resources to allow additional virtual machines to be installed, to run an approved list of applications:

• A Windows Server with the following services:
  • DHCP
  • Active Directory domain controller
  • DNS service
• A print server
• An antivirus server

The following limitations apply to installing additional virtual machines:

• Additional virtual machines can be installed using the VMware Host Client only. That is, you cannot use vSphere vCenter to manage either the CTERA Edge Filer nor any additional virtual machines.
• A maximum of two additional virtual machines can be installed on the ESXi.
• A maximum of two vCPUs that can be defined in the VMware Host Client for the additional virtual machines. That is, either one virtual machine with two vCPUs or two virtual machines, each with one vCPU.
• The memory allocated to additional virtual machines is limited to a total of 28GB.
• The storage allocated to additional virtual machines can use all the available free storage, which is around 1TB.
• Additional virtual machines must be connected to a separate virtual switch, not used by the CTERA Edge Filer, with an uplink to separate physical NICs.
• Customer may configure the additional virtual machines to autostart with the ESXi, but they must leave the CTERA Edge Filer as the first virtual machines to autostart.
• When installing a Windows Server, it must be Windows Server 2008 R2 or later.
  Installing virtual machines has the following impact on the CTERA Edge Filer:
• Prior to installing the virtual machines, the ESXi host must be secured, as described in the procedure below. This requires rebooting the ESXi host, resulting in downtime for the CTERA Edge Filer.
• The performance of the CTERA Edge Filer might be degraded after installing a virtual machine.
  :::(Info) (Note)In tests performed by CTERA Networks Ltd., the performance of the CTERA Edge Filer could degrade by as much as 20%.
