How to replace a blade

This section contains instructions on how to gracefully remove and replace a malfunctioning hardware blade running one of the Security Event Manager hosts in an active system. In order to allow the high availability mechanism to take effect, only one blade can be decommissioned at a time.

Finding a blade's location A blade’s host name is follows a naming convention: blade-10-0-{chass ID}-{blade ID}. A blade named "blade-10-0-1-3" means that "1" represents the chassis ID and the "3" represents the blade ID. Therefore, the blade is the third blade to the left on the first chassis. The internal IP of the blade is 10.0.1.3.

There are three types of host roles: Master Node, MetaStore Node and Data Node (see Roles). You can find the role type of a host in Cluster Manager > Hosts. Some role types require a different method for replacement.

• Replace a blade with the Data Node role
• Replace a blade with the Master Node or MetaStore Node role

Before proceeding with the steps below, your version of FortiAnalyzer-BigData bootloader must match your current version of FortiAnalyzer-BigData. If you do not know the version of your bootloader, it is recommended that you upgrade the bootloader before proceeding. To upgrade the bootloader, see Upgrade Bootloader.

To replace a blade with the Data Node role:

1. Connect to the Security Event Manager Controller (see To connect to the Security Event Manager Controller:) and run the following command to decommission the host by its IP address:
   fazbdctl delete {member_ip_addr}
2. Power off the blade, and then remove the blade from the chassis.
3. Insert the replacement blade, and power it on.
4. From the bootloader (see Bootloader), set the chassis ID and the blade ID of the replacement blade to match the one from Cluster Manager > Hosts.
5. Reconnect to the Security Event Manager Controller and run the following command to ensure that the new blade has joined the cluster:
   fazbdctl show members
6. If the output for the newly added blade shows as "need upgrade", run the following command to upgrade that specific blade:
   fazbdctl reset {member_ip_addr}
7. After the host status changes to "Alive" in the command from step 5, the host will show up in Cluster Manager > Hosts.
8. From the Hosts page, click Assign Role to add the host.
   The newly added host should have a "new" label.

When the Assign Role job completes, the blade replacement is done.

To replace a blade with the Master Node or MetaStore Node role:

1. Go to Cluster Manager > Services > Actions and select Stop All Services.
2. Power off the blade, and then remove the blade from the chassis.
3. Insert the replacement blade, and power it on.
4. Go to the bootloader (see Bootloader) and do the following:
   1. Set the Role to Worker.
   2. Set the chassis ID and the blade ID of the replacement blade to match Cluster Manager > Hosts.

      If the blade role is not set correctly, the cluster might not function properly.

5. Connect to the Security Event Manager Controller (see To connect to the Security Event Manager Controller:) and run the following command to ensure that the new blade has joined the cluster:

   fazbdctl show members

6. If the output for the newly added blade shows need upgrade, run the following command to upgrade that specific blade: fazbdctl reset {member_ip_addr}
7. After the host status changes to Alive from the command in step 5, go to the bootloader (see Bootloader) and do the following:
   1. In step 4 b above, if the replacement blade ID is set to 2 and the chassis ID is set to 1, then set the Role to Controller.
   2. Connect to the Security Event Manager Controller (see To connect to the Security Event Manager Controller:) and run the following command to soft reset FortiAnalyzer-BigData (see Soft reset FortiAnalyzer-BigData):

      fazbdctl reset cluster

When the soft reset completes, the blade replacement is done.
