You might need to perform maintenance procedures on the appliance. The procedures in this section assume that the appliance has already been deployed as a Gateway Node or an Admin Node in a StorageGRID system.
Replacing the services appliance
You might need to replace the appliance if it is not functioning optimally or if it has failed.
Replacing a power supply in the services appliance
The services appliance has two power supplies for redundancy. If one of the power supplies fails, you must replace it as soon as possible to ensure that the appliance has redundant power.
Replacing a fan in the services appliance
The services appliance has eight cooling fans. If one of the fans fails, you must replace it as soon as possible to ensure that the appliance has proper cooling.
Replacing a drive in the services appliance
The SSDs in the services appliance contain the StorageGRID operating system. Additionally, when the appliance is configured as an Admin Node, the SSDs also contain audit logs, metrics, and database tables. The drives are mirrored using RAID1 for redundancy. If one of the drives fails, you must replace it as soon as possible to ensure redundancy.
Changing the link configuration of the SG1000
You can change the Ethernet link configuration of the SG1000. You can change the port bond mode, the network bond mode, and the link speed.
Changing the MTU setting
You can change the MTU setting that you assigned when you configured IP addresses for the appliance node.
