You can view information about a StorageGRID Webscale appliance Storage Node at any time. For example, you might want to review appliance-specific information to ensure correct configuration and status.
Each StorageGRID Webscale appliance is represented as one Storage Node.
The StorageGRID Webscale appliance Storage Node lists information about service health and all computational, disk device, and network resources. You can also see memory, storage hardware, network resources, network interfaces, network addresses, and receipt and transmittal information.
The Worldwide Name for each disk matches the volume world-wide identifier (WWID) that appears when you view standard volume properties in SANtricity software (the management software connected to the appliance's storage controller).
To help you interpret disk read and write statistics related to volume mount points, the first portion of the name shown in the Device column of the Disk Devices table (that is, sdc, sdd, sde, and so on) matches the value shown the Device column of the Volumes table on the SSM > Resources page.
This section appears only if the Storage Node is an appliance.
Field | Description |
---|---|
Storage Controller Name | The name for this StorageGRID Webscale appliance shown in SANtricity software. |
Storage Controller Management IP | IP address for management port 1 on the storage controller. You use this IP to access SANtricity software to troubleshoot storage issues. |
Storage Controller Model | The type of enclosure used for the appliance: 2u12 is two rack-units high with 12 drives, 4u60 is four rack-units high with 60 drives. |
Storage Controller WWN | The worldwide identifier of the storage controller, as shown in SANtricity software. |
Storage Appliance Chassis Serial Number | The serial number for the appliance. |
Software Platform | The software platform used to generate the storage hardware status and alarms. |
Overall Power Supply Status | The status of power to the StorageGRID Webscale appliance. |
Power Supply A Status Power Supply B Status |
The status of power supplies A and B in the StorageGRID Webscale appliance. |
CPU Temperature | The temperature of the CPU in the compute controller. |
Module Temperature | The temperature of the compute controller. |
Multipath State | The current multipath I/O state of the physical paths, for example, Simplex or Nominal. If one of the connections between the two controllers is not operational, "Simplex" appears and performance and fault tolerance are impacted. If both paths are not operational, the appliance stops working. For details about resolving performance or fault tolerance issues, refer to the E-Series documents. |
Storage Controller Status | The overall status of the storage controller. If the Storage Node is a StorageGRID Webscale appliance and it needs attention, then both the StorageGRID Webscale and SANtricity systems indicate that the storage controller needs attention. If the status is "needs attention," first check the storage controller using SANtricity software. Then, ensure that no other alarms exist that apply to the compute controller. |
Field | Alarm code |
---|---|
Overall Power Supply Status | OPST |
Power Supply A Status or Power Supply B Status | PSAS or PSBS |
CPU Temperature | CPUT |
Module (Board) Temperature | BRDT |
Storage Controller Status | SOSS |
For details about alarms in StorageGRID Webscale, see the Troubleshooting Guide.
Network | Interface name | Physical port name |
---|---|---|
Grid | eth0 | hic2 and hic4 The Grid Network connects to the 10/25-GbE (optical) network ports on the compute controller. Port 2 is named hic2, and port 4 is named hic4. |
Admin | eth1 | mtc1 and mtc2 The Admin Network connects to the leftmost 1-Gb (RJ-45) Ethernet port on the compute controller. Port 1 is named mtc1. Port 2 (mtc2) is used only for installation and service operations. |
Client (optional) | eth2 | hic1 and hic3 The Client Network connects to the 10/25-GbE (optical) network ports on the compute controller. Port 1 is named hic1, and port 3 is named hic3. |
See the Hardware Installation and Maintenance Guide for your appliance for more information about configuring the 10/25-GbE ports.
