I/O module failure or removal results in a large number of alerts for degraded drives

Problem

When the I/O module from the storage shelf fails or is removed, an alert is sent for each drive that shows the status as Degraded. After the I/O module issue is fixed, the same number of resolution emails are sent.

Error Message

The email alert includes content similar to the following:

• The disk drive is either not always responding or not fully operational
• Time of event: 2025-05-12 15:21:50 (+00:00)
• UMI event code: V-475-500-0201
• Component type: Disk
• Component: ExpansionShelf 2 Drawer 0 Slot 12
• Status: Degraded
• State: WARNING
• Additional information about this error is available at the following link:
V-475-500-0201

Cause

When the I/O module fails or is removed, the data path to the drive is no longer redundant. Therefore, all of the drives go into a Degraded state, which is expected behavior.

As per the current design of the storage monitoring plug-in, separate alerts are sent for each of the drives, which results in a large number of alerts.

Solution

In this scenario, the alerts can be ignored.
