Troubleshooting SRP Issues
Solution 1:
The host initiator has not been configured as an SRP initiator on the VIO
hardware SRP Initiator Discovery screen. Via Chassis Viewer, bring up the SRP
Initiator Discovery screen and either
Click on 'Add New' to add a wildcarded entry with the initiator extension to
match what is in the session entry in the qlgc_srp.cfg file, or
Click on the Start button to discover the adapter port GUID, and then click
'Configure' on the row containing the adapter port GUID and give the entry
a name.
Solution 2:
Check the SRP map on the VIO hardware specified in the failing Session block of
the qlgc_srp.cfg file. Make certain there is a map defined for the row specified
by either the initiatorExtension in the failing Session block of the
qlgc_srp.cfg file or the adapter port GUID specified in the failing Session block
of the qlgc_srp.cfg file. Additionally, make certain that the map in that row is in
the column of the IOC specified in the failing Session block of the qlgc_srp.cfg
file.
Attempts to read or write to disk are unsuccessful
Problem:
Attempts to read or write to the disk are unsuccessful when SRP comes up. About
every five seconds the VIO hardware displays
"fcIOStart Failed",
"CMDisconnect called for Port: xxxxxxxx Initiator: Target: ",
and
"Target Port Deleted for Port: xxxxxxxx Initiator: Target: "
The host log shows a session transitioning between Connected and Down. The
host log also displays "Test Unit Ready has FAILED", "Abort Task has
SUCCEEDED", and "Clear Task has FAILED".
Solution:
This indicates a problem in the path between the VIO hardware and the target
storage device. After an SRP host has connected to the VIO hardware
successfully, the host sends a "Test Unit Ready" command to the storage
device. After five seconds, if that command is not responded to, the SRP host
brings down the session and retries in five seconds. Verify that the status of the
connection between the appropriate VIO hardware port and the target device is
UP on the FCP Device Discovery screen.
