Diagnosing and Correcting FC-AL Loop Problems
8-17
■
ofdg
does not detect missing loop cables.
■
ofdg
output goes to the
syslog
and serial port only.
■
ofdg
assumes at least one back-end loop cable is functional.
After installing a new drive, wait two minutes before running
ofdg
. Follow these
steps to run
ofdg
:
1. Perform an
ofdg health_check
operation.
All loops are given either a Go or No-Go status.
■
If there is a Go status, this indicates that the
ofdg
test did not detect any
problems with the configuration and that there is no need for further tests.
■
If there is a No-Go status, proceed to the next step.
2. Perform an
ofdg fast_test
operation.
All loops are given either a Go or No-Go status.
■
If there is a Go status, this indicates that the
ofdg
test did not detect any
problems with the configuration and that there is no need for further tests.
■
If there is a No-Go status, proceed to the next step.
3. Perform an
ofdg fast_find
operation.
The loop is given a Go or No-Go status with progress indications. If a failure is
reported on the first or nearest enclosure then the loop card in that enclosure should
be swapped before repeating the test with the next unit.
If a failure is reported for the second (or further) enclosure,
fast_find
isolates the
bad FRU(s) to either a bad interconnect cable or the two interconnect cards (which
are connected to the interconnect cable in question). In this case,
fast_find
should
be run from the partner controller to eliminate some FRUs.
