Detecting issues

The SMART (Self-Monitoring, Analysis and Reporting Technology system) status of SSDs can be monitored. SMART technology monitors and informs about the status of certain reliability indicators such as the temperature, number of sectors allocated, errors while locating sectors, etc. It therefore helps to anticipate failures.

On SN910, SN-M-Series-520, SN-M-Series-720, SN-M-Series-920, SN1100 and SN2100 models without the RAID option, and on SNi20 and SNi40 models, the SMART status of the SSD is available in the Hardware section of the Hardware widget.

On SN2100 models with the RAID option, and on SN3100, SN-L-Series-2200, SN-L-Series-3200, SN6100, SN-XL-Series-5200 and SN-XL-Series-6200 models, the RAID section in the Hardware widget informs you about the SMART status of the SSDs, as well as the RAID status.

You may also log on to the appliance in console mode or via an SSH connection and obtain the information with the following commands:

• SMART status of the SSDs: smartinfo,
• If SSDs are installed in RAID: nraid -s,

If an issue arises with the log partition, report it using the Properties widget either in console mode or via an SSH connection, using the command: logdisk –c, the partition can be rebuilt using the following command: logdisk –f.

IMPORTANT
This command permanently erases data saved earlier on the log partition.

If the SMART status of an SSD shows errors, or if rebuilding your log partition fails, you can contact your certified partner to replace your SSD.
