This basetype is used by show configuration and show pools.

Table 1. pools properties
Name	Type	Description

blocksize	uint32	The size of a block, in bytes.
total-size	string	The total capacity of the pool.
total-size-numeric	unit64	Unformatted total-size value in blocks.
total-avail	string	The available capacity in the pool.

snap-size	string	Not applicable.
snap-size-numeric	unit64	Not applicable.
allocated-pages	uint32	For a virtual pool, the number of 4 MB pages that are currently in use. For a linear pool, 0.
available-pages	uint32	For a virtual pool, the number of 4 MB pages that are still available to be allocated. For a linear pool, 0.
overcommit	string	Disabled: The allocated size of the volumes cannot exceed the physical capacity of the pool. Enabled: The allocated size of the volumes can exceed the physical capacity of the pool. N/A: Not applicable (linear pool).
overcommit-numeric	uint32	Numeric equivalents for overcommit values. 0: Disabled 1: Enabled 2: N/A
over-committed	string	True: The pool is overcommitted. False: The pool is not overcommitted.
over-committed-numeric	uint32	Numeric equivalents for over-committed values. 0: Disabled 1: Enabled
disk-groups	uint16	The number of disk groups in the pool.
volumes	uint16	The number of volumes in the pool.
page-size	string	The page size, formatted to use the current base, precision, and units.
page-size-numeric	uint64	Unformatted page-size value in blocks.
low-threshold	string	The low threshold for page allocation as a percentage of pool capacity.
middle-threshold	string	The middle threshold for page allocation as a percentage of pool capacity.
high-threshold	string	The high threshold for page allocation as a percentage of pool capacity. The threshold value is automatically calculated based on the available capacity of the pool minus 200 GB of reserved space.
utility-running	string	Job running on the disk, if any. (blank): None. DRSC: The disk group is being scrubbed. EXPD: The disk group is being expanded. INIT: The disk group is being initialized. RBAL: The ADAPT disk group is being rebalanced. RCON: At least one disk in the disk group is being reconstructed. VDRAIN: The virtual disk group is being removed and its data is being drained to another disk group. VPREP: The virtual disk group is being prepared for use in a virtual pool. VRECV: The virtual disk group is being recovered to restore its membership in the virtual pool. VREMV: The disk group and its data are being removed. VREMV: The disk group and its data are being removed. VRFY: The disk group is being verified. VRSC: The disk group is being scrubbed.

preferred-owner	string	Controller that owns the disk group and its volumes during normal operation. A: Controller A. B: Controller B.
preferred-owner-numeric	uint32	Numeric equivalents for preferred-owner values. 0: B 1: A
owner	string	Current owner, which is either the preferred owner during normal operation or the partner controller when the preferred owner is offline. A: Controller A. B: Controller B.
owner-numeric	uint32	Numeric equivalents for owner values. 0: B 1: A

idle-page-check	string	For internal use only.
idle-page-check-numeric	uint32	For internal use only.
read-flash-cache	string	For internal use only.
read-flash-cache-numeric	uint32	For internal use only.
metadata-vol-size	string	The size of the pool’s metadata volume, formatted to use the current base, precision, and units. This needs to be taken into consideration to account for all pages in the pool that are used.
metadata-vol-size-numeric	uint64	Unformatted metadata-vol-size value in blocks.
total-rfc-size	string	The total size in blocks of the read cache in the pool.
total-rfc-size-numeric	uint64	Unformatted total-rfc-size value in blocks.
available-rfc-size	string	The unused read-cache space in blocks that is available for use by the pool.
available-rfc- size-numeric	uint64	Unformatted available-rfc-size value in blocks.
reserved-size	string	The total number of pages that are reserved for virtual volumes in the pool.
reserved-size-numeric	unit64	Unformatted reserved-size value in blocks.
reserved-unalloc-size	string	The total number of pages that are reserved, but not yet allocated, for virtual volumes in the pool.
reserved-unalloc-size-numeric	unit64	Unformatted reserved-unalloc-size value in blocks.
pool-sector-format	string	The sector format of disks in the disk group. 512n: All disks use 512-byte native sector size. Each logical block and physical block is 512 bytes. 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).
