Name Type Description
fc-p1-node-wwn string Port 1 WWNN.
fc-p1-port-wwn string Port 1 WWPN.
fc-p1-unit-number uint32 Port 1 unit number.
fc-p2-channel uint32 Port 2 channel number.
fc-p2-device-id uint32 Port 2 device ID.
fc-p2-node-wwn string Port 2 WWNN.
fc-p2-port-wwn string Port 2 WWPN.
fc-p2-unit-number uint32 Port 2 unit number.
drive-down-code uint8 Numeric code indicating why the disk is down.
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
index uint32 For internal use only.
rpm uint32 The speed of a spinning disk, in thousands of revolutions per minute, as specified
by the disk vendor. For an SSD, 0 is shown.
size string Disk capacity, formatted to use the current base, precision, and units.
size-numeric uint64 Unformatted size value in blocks.
sector-format string The disk sector format.
● 512n: The disk uses 512-byte native sector size. Each logical block and
physical block is 512 bytes.
● 512e: The disk uses 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.
sector-format-numeric uint32 Numeric equivalents for sector-format values.
● 0: 512n
● 1: 512e
transfer-rate string Disk data transfer rate in Gbit/s. It is normal behavior for the rate to vary.
● 1.5
● 3.0
● 6.0
Some 6 Gbit/s disks might not consistently support a 6 Gbit/s transfer rate.
If this happens, the controller automatically adjusts transfers to those disks to3
Gbit/s, increasing reliability and reducing error messages with little impact on
system performance. This rate adjustment persists until the controller is restarted
or power-cycled.
transfer-rate-numeric uint32 For internal use only.
attributes string Shows which controller a single-ported disk is connected to.
● A: Controller A.
● B: Controller B.
NOTE: ME4 Series systems support only dual-ported disks.
