The following items are reported in the table above. All counts are hexadecimal:
• Phy number – Links are individual Phys, numbered 0 through 31 on J830s
units, and 0 through 23 on J630s units.
The Link Status list matches Phy number to Slot or Connector number,
where you can identify the disk drive or external SAS port reported in the
Link Counter. See page 38.
• Type – Physical drive slots or connectors. Each slot has one Phy. See "Drive
Numbering" on page 19.
CN#1 and CN#2 represent the external SAS connectors. Each connector
has four Phys. CN#1 is the SAS IN port, CN#2 is the SAS OUT port.
See Figure 4 on page 30.
• Invalid D-word Count
• Disparity Error Count
• PHY Reset Problem Count

DsEr: Disparity Err Count
PhRe: Phy Reset Problem Count
PhCh: Phy Change Count
If the count is zero, the counter shows
dashes (----------).
The fact that errors occur does not
necessarily indicate a link problem or that
the VTrak unit is malfunctioning.
However, an individual error count that
increments regularly does indicate a
possible problem and requires further
investigation.
