The STATUS SERVERNET command displays a matrix for the ServerNet X fabric and Y fabric. Each
matrix shows the status of the path between all pairs of processors. The status (st) can be:
(disabled) A ServerNet fabric is down at the “TO” location. As a result, the path from the “FROM”
processor to the “TO” processor is down for receiving, which means that the “TO” processor cannot
receive from any other processor or from I/O devices on that fabric. DIS overrides UP and DN.
DIS
(down) The path from the FROM processor to the TO processor is down because the path is failing.
The FROM processor cannot communicate with the TO processor on that fabric.
DN
(across a row) The FROM processor is down or nonexistent.<-DOWN
(across a row) The FROM processor unexpectedly returned file-system error nnn to the ServerNet
fabric. For information about the file-system error, see the Guardian Procedure Errors and Messages
Manual.
ERRORnnn
(unavailable) The link from the FROM processor to the “TO” processor is down because the TO
processor is down or nonexistent. UNA overrides all other values.
UNA
The path from the FROM processor to the TO processor is up.UP
