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

To replace a blade with the Data Node role:

1. Access 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 -c delete -h {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 -c show -t members
6. If the output for the newly added blade shows as "need upgrade", run the following command to upgrade that specific blade:
   fazbdctl -c upgrade -t bd -h {member_ip_addr}
7. After the host status changes to "Joined" 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.
9. Once the “Assign Role” job finishes running, 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. From the bootloader (see Bootloader), set the chassis ID and the blade ID of the replacement blade to match Cluster Manager > Hosts.
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 -c show -t members
6. If the output for the newly added blade shows as "need upgrade", run the following command to upgrade that specific blade:
   fazbdctl -c upgrade -t bd -h {member_ip_addr}
7. After the host status changes to "Joined" in the command from step 5, run the following command to soft reset FortiAnalyzer-BigData (see Soft reset FortiAnalyzer-BigData):
   fazbdctl -c reset -h cluster
8. After the soft reset is finished, the blade replacement is done.
