The following example of
CQUERY PATHS printed output displays data for a storage control that
supports eight paths. It includes FCP pathing information. Path information
for paths 5-8 would not be displayed if fewer than five paths were
active, or if the storage control supported only four paths.

For a description of the fields, refer to Fields in formatted output.
The
path status codes are defined as follows.
Path codes noted as "LSS
only" are valid only for storage subsystems that support logical
storage subsystems. - 00 — NO PATH
- The request to establish this path is in process, or you have
not requested this entry. (The SAID/DEST appears as "----" until
the CESTPATH command operation has completed. Reissue the CQUERY command
with the PATHS option.)
- 01 — ESTABLISHED
- Path is operational.
- 02 — INIT FAILED
- An attempt to establish this path has failed. Verify that the
physical link, including ESCD ports, is correct for the connection
you are attempting. Verify the integrity of the fiber-optic links
between the requested source and the destination.
- 03 — TIME OUT
- An attempt to establish this path has failed. Verify the physical
link at the primary storage control. Determine if non-PPRC system
activity has degraded link response times during the establish time.
Retry the CESTPATH command.
- 04 — NO RESOURCES AT PRI
- An attempt to establish this path has failed. Verify that the
primary storage control does not already have the maximum number of
logical paths already established. Verify the configuration and remove
any unnecessary channel paths. When the problem is resolved, issue
a CQUERY command with the PATHS option to verify that the path has
been automatically established.
- 05 — NO RESOURCES AT SEC
- An attempt to establish this path has failed. Verify that the
recovery site storage control does not already have the maximum number
of logical paths already established. Verify the configuration and
remove any unnecessary channel paths. When the problem is resolved,
issue a CQUERY command with the PATHS option to verify that the path
has been automatically established.
- 06 — SERIAL # MISMATCH
- The recovery site storage control specified by the SAID/DEST does
not have the same serial number specified in the CESTPATH command.
Verify the SAID/DEST port and the serial number parameters. A CQUERY
command with the PATHS option from the host to a secondary volume
can provide the serial number information.
- 07 — SEC SSID MISMATCH
- (LSS only) An attempt to establish this path has failed. Verify
that the path is available and is properly defined, and then retry
the CESTPATH command.
- 08 — ESCON® LINK OFFLN
- (LSS only) An attempt to establish this path has failed. Retry
the CESTPATH command after you have made a path available.
- 09 — ESTABLISH FAILED
- (LSS only) An attempt to establish this path has failed. If the
automatic attempts to reconnect are not successful, reissue the CESTPATH
command.
- 0A — PATH ACTIVE TO HOST
- (LSS only) An attempt to establish this path has failed. The system
adapter has already established a link to the system server on this
path. Retry the CESTPATH command, specifying another path.
- 0B — PATH TO SAME CLUSTR
- (LSS only) An attempt to establish this path has failed because
there is already an established path from this primary cluster to
this secondary cluster.
- 10 — CONFIGURATION ERROR
- The SAID is not valid for the primary site storage control ESCON SA card, or a PPRC path
has already been established on this logical link. Verify the SAID
is appropriate for the number of physical ESCON ports installed on the primary storage
control SA card. Also, determine if this is already a PPRC logical
path, possibly established in the other direction. To do this, issue
a CQUERY command with the PATHS option to the indicated storage controls
at both sites.
- 13 — Fibre Path Established
- 14 — Fibre Channel Path Link Down
- 15 — Fibre Channel Path Retry Exceeded
- 16 — Fibre Channel Path Secondary Adapter not PPRC Capable
- Some possible reasons for this status displaying are as follows:
- Secondary adapter is not configured properly, or does not have
the correct version of microcode loaded.
- The secondary adapter is already a target of 32 different ESS
boxes.
- 17 — Fibre Channel Path Secondary Adapter not Available
- 18 — Fibre Channel Path Primary Login Exceeded
- 19 — Fibre Channel Path Secondary Login Exceeded
- 1B — FIBRE DEGRADED
- Fibre Channel Path established, but degraded due to high failure
rate.
- 1C — FIBRE REMOVED
- Fibre Channel Path removed with high failure rate.
