Table 30. disk-group-statistics properties (continued)
Name Type Description
data-written string Amount of data written since these statistics were last reset or since the
controller was restarted.
data-written-numeric uint64 Unformatted data-written value.
bytes-per-second string The data transfer rate, in bytes per second, calculated over the interval since
these statistics were last requested or reset. This value will be zero if it has not
been requested or reset since a controller restart.
bytes-per-second-numeric uint64 Unformatted bytes-per-second value.
iops uint32 Input/output operations per second, calculated over the interval since these
statistics were last requested or reset. This value will be zero if it has not been
requested or reset since a controller restart.
avg-rsp-time uint32 Average response time in microseconds for read and write operations, calculated
over the interval since these statistics were last requested or reset.
avg-read-rsp-time uint32 Average response time in microseconds for all read operations, calculated over
the interval since these statistics were last requested or reset.
avg-write-rsp-time uint32 Average response time in microseconds for all write operations, calculated over
the interval since these statistics were last requested or reset.
disk-group-statistics-paged Embedded; see disk-group-statistics-paged on page 323.
disk-group-statistics-paged
This basetype is used by show disk-group-statistics on page 182 for a virtual disk group.
Table 31. disk-group-statistics-paged properties
Name Type Description
serial-number string The serial number of the disk group.
pages-alloc-per-minute uint32 The rate, in pages per minute, at which pages are allocated to volumes in the disk
group because they need more space to store data.
pages-dealloc-per-minute uint32 The rate, in pages per minute, at which pages are deallocated from volumes in
the disk group because they no longer need the space to store data.
pages-reclaimed uint32 The number of 4 MB pages that have been automatically reclaimed and
deallocated because they are empty (they contain only zeroes for data).
num-pages-unmap-per-
minute
uint32 The number of 4 MB pages that host systems have unmapped per minute,
through use of the SCSI UNMAP command, to free storage space as a result
of deleting files or formatting volumes on the host.
disk-hist-statistics
This basetype is used by show disk-statistics on page 190 when the historical parameter is specified.
Table 32. disk-hist-statistics properties
Name Type Description
number-of-ios uint64 Total number of read and write operations since the last sampling time.
number-of-reads uint64 Number of read operations since the last sampling time.
number-of-writes uint64 Number of write operations since the last sampling time.
