CLI Guide

• 512e: All disks use 512-byte emulated sector size. Each logical block is 512 bytes and each physical block
is 4096 bytes. Eight logical blocks will be stored sequentially in each physical block. Logical blocks may or
may not be aligned with physical block boundaries.
• Mixed: The disk group contains a mix of 512n and 512e disks. This is supported, but for consistent and
predictable performance, do not mix disks of different sector size types (512n, 512e).
Sector Format
Shown by the detail parameter. See Sec Fmt, above.
Serial Number
Shown by the detail parameter. The serial number of the disk group.
Size
The capacity of the disk group, formatted to use the current base, precision, and units.
Spares
Shown by the detail parameter. For a linear disk group, the number of spares assigned to the disk group.
For a virtual disk group, 0.
Status
• CRIT: Critical. The disk group is online but isn't fault tolerant because some of its disks are down.
• DMGD: Damaged. The disk group is online and fault tolerant, but some of its disks are damaged.
• FTDN: Fault tolerant with a down disk. The disk group is online and fault tolerant, but some of its disks are
down.
• FTOL: Fault tolerant and online.
• MSNG: Missing. The disk group is online and fault tolerant, but some of its disks are missing.
• OFFL: Offline. Either the disk group is using offline initialization, or its disks are down and data may be
lost.
• QTCR: Quarantined critical. The disk group is critical with at least one inaccessible disk. For example, two
disks are inaccessible in a RAID-6 disk group 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 disk group is QTCR
or QTDN, the disk group is automatically dequarantined.
• QTDN: Quarantined with a down disk. The RAID-6 disk group has one inaccessible disk. The disk group is
fault tolerant but degraded. If the inaccessible disks come online or if after 60 seconds from being
quarantined the disk group is QTCR or QTDN, the disk group is automatically dequarantined.
• QTOF: Quarantined offline. The disk group is offline with multiple inaccessible disks causing user data to
be incomplete, or is an NRAID or RAID-0 disk group.
• STOP: The disk group is stopped.
• UNKN: Unknown.
• UP: Up. The disk group is online and does not have fault-tolerant attributes.
Tier
• Performance: The disk group is in the highest storage tier, which uses SSDs (high speed).
• Standard: The disk group is in the storage tier that uses enterprise-class spinning SAS disks (10k/15k
RPM, higher capacity).
• Archive: The disk group is in the lowest storage tier, which uses midline spinning SAS disks (<10k RPM,
high capacity).
• Read Cache: The disk is an SSD providing high-speed read cache for a storage pool.
