EVO uses enterprise-class disks with industry-leading expected lifetimes, but like any hardware component, a disk may fail at any time.
EVO continually monitors the health of these disks, and if a drive does fail, it will attempt to raise awareness in a few ways:
1. The system should start sounding an audible beep alarm. It's possible to silence the audible alarm from the EVO's Alerts page.
2. A red LED should start flashing on the drive tray for the failed disk.
3. If SMTP notifications have been configured, an email alert will be sent to the designated recipient(s).
4. If SNMP has been configured, the SNMP manager will be notified.
5. The EVO web interface should also show the concern corresponding to the location of the disk in the chassis.
Consult the EVO guide, accessible by clicking Help in the menu, and navigate to the EVO Disks & Pools page for step-by-step instructions for replacing the failed disk.
Once the new drive is committed, the EVO will begin to self-repair the affected pool.
We recommend always having a spare drive available. If you experience a disk failure, contact us to find out if it's under SNS hardware coverage.
