MSA 2040 SMU Reference Guide

Viewing information about all vdisks 101
When reviewing events, do the following:
1. For any critical, error, or warning events, click the message to view additional information and recommended
actions. This information also appears in the Event Descriptions Reference Guide.
Identify the primary events and any that might be the cause of the primary event. For example, an
over-temperature event could cause a disk failure.
2. View the event log and locate other critical/error/warning events in the sequence for the controller that reported
the event.
Repeat this step for the other controller if necessary.
3. Review the events that occurred before and after the primary event.
During this review you are looking for any events that might indicate the cause of the critical/error/warning event.
You are also looking for events that resulted from the critical/error/warning event, known as secondary events.
4. Review the events following the primary and secondary events.
You are looking for any actions that might have already been taken to resolve the problems reported by the
events.

Viewing information about all vdisks
In the Configuration View panel, right-click Vdisks and select View > Overview. The Vdisks Overview table shows:
• Health.
OK
Degraded
Fault
Unknown
• Component.
• Count. Number of components.
• Capacity. Total capacity of the component.
• Storage Space. Amount of space on the component. For descriptions of storage-space color codes, see "About
storage-space color codes" (page 29).
The Vdisks table shows more information about each vdisk.
• Health.
• Name. Vdisk name.
• Size. Total storage space in the vdisk.
• Free. Available space in the vdisk.
• RAID. RAID level of the vdisk and all of its volumes.
• Status.
• CRIT: Critical. The vdisk is online but isn’t fault tolerant because some of its disks are down.
• FTDN: Fault tolerant with a down disk. The vdisk is online and fault tolerant, but some of its disks are down.
• FTOL: Fault tolerant and online.
• OFFL: Offline. Either the vdisk is using offline initialization, or its disks are down and data may be lost.
• QTCR: Quarantined critical. The vdisk is critical with at least one inaccessible disk. For example, two disks are
inaccessible in a RAID-6 vdisk or one disk is inaccessible for other fault-tolerant RAID levels. If the inaccessible
disks come online or if after 60 seconds from being quarantined the vdisk is QTCR or QTDN, the vdisk is
automatically dequarantined.
• QTDN: Quarantined with a down disk. The RAID-6 vdisk has one inaccessible disk. The vdisk is fault tolerant
but degraded. If the inaccessible disks come online or if after 60 seconds from being quarantined the vdisk is
QTCR or QTDN, the vdisk is automatically dequarantined.
• QTOF: Quarantined offline. The vdisk is offline with multiple inaccessible disks causing user data to be
incomplete, or is an NRAID or RAID-0 vdisk.
