• 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. • STOP: The vdisk is stopped. • UNKN: Unknown. • UP: Up. The vdisk is online and does not have fault-tolerant attributes. • Current Job. If a utility is running on the vdisk, this field shows the utility's name and progress. • Disk Scrub: Disks in the vdisk are being scrubbed. • Expand: The vdisk is being expanded. • Initialize: The vdisk is being initialized. • Reconstruct: The vdisk is being reconstructed. • Verify: The vdisk is being verified. • Media Scrub: The vdisk is being scrubbed. • Drive Spin Down Vdisk Enable. Shows whether drive spin down is enabled or disabled for this vdisk. A second table displays information about unhealthy components. If all components are healthy, this table displays the text, "There is no data for your selection." NOTE: In the Configuration View panel, if a vdisk contains more than one type of disk, its RAID-level label includes the suffix -MIXED. Vdisk performance When you select Vdisk in the Vdisk Overview table and click the Performance tab, the Performance Statistics panel shows three graphs of historical performance statistics for the vdisk: Data Transferred, Data Throughput, and Average Response Time. Data samples are taken every quarter hour and the graphs represent up to 50 samples. To specify a time range of samples to display, set the start and end values and click Update. The system determines whether the number of samples in the time range exceeds the number of samples that can be displayed (50), requiring aggregation. To determine this, the system divides the number of samples in the specified time range by 50, giving a quotient and a remainder. If the quotient is 1, the 50 newest samples will be displayed. If the quotient exceeds 1, each "quotient" number of newest samples will be aggregated into one sample for display. The remainder is the number of oldest samples that will be excluded from display. • Example 1: A 1-hour range includes 4 samples. 4 is less than 50 so all 4 samples are displayed. • Example 2: A 15-hour range includes 60 samples. 60 divided by 50 gives a quotient of 1 and a remainder of 10. Therefore, the newest 50 samples will be displayed and the oldest 10 samples will be excluded. • Example 3: A 30-hour range includes 120 samples. 120 divided by 50 gives a quotient of 2 and a remainder of 20. Therefore, each two newest samples will be aggregated into one sample for display and the oldest 20 samples will be excluded. Viewing information about a vdisk 101
