Description
Shows diagnostic information relating to SAS controller physical channels, known as PHY lanes, for
each host port.
This command shows PHY status information for each host port found in an enclosure. Each
controller in an enclosure may have multiple host ports. A host port may have multiply PHYs. For
each PHY, this command shows statistical information in the form of numerical values.
There is no mechanism to reset the statistics. All counts start from the time the controller started up.
The counts stop at the maximum value for each statistic.
This command is only applicable to systems that have controllers with SAS host ports.

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
