Syntax
show host-phy-statistics
Output
Ports
The controller ID and port number of the SAS host ports for which PHY statistics are displayed.
Phy
Identifies a PHY’s logical location within a group based on the PHY type. Logical IDs are 0–3 for host port
PHYs. Each SAS host will have multiple PHYs.
Disparity
The number of doublewords containing running disparity errors that have been received by the PHY, not
including those received during Link Reset sequences. A running disparity error occurs when positive and
negative values in a signal do not alternate.
Lost DWORD
The number of times the PHY has lost doubleword synchronization and restarted the Link Reset sequence.
Invld DWORD
The number of invalid doublewords that have been received by the PHY, not including those received during
Link Reset sequences.
ResErrCnt
The number of times the PHY Reset sequence has failed
Examples Show PHY statistics for controller host ports.

show host-port-statistics
show host-port statistics
Description
Shows live performance statistics for each controller host port. For each host port these statistics quantify
I/O operations through the port between a host and a volume. For example, each time a host writes to a
volume’s cache, the host port’s statistics are adjusted. For host-port performance statistics, the system
samples live data every 15 seconds.
Statistics shown only in API output are described in API basetypes properties.

Syntax
show host-port-statistics
[ports ports]
Parameters
ports ports
Optional. Specifies a comma-separated list of port IDs for which to show information. For port syntax, see
Command syntax. If this parameter is omitted, information is shown for all host ports.
Output
Durable ID
The host port ID in the format hostport_controller-ID-and-port-number.
Bps
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.
IOPS
The 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.
