Nov 4 09:14:12 exampledb kernel: qla2xxx [0000:0c:00.0]-801c:7: Abort command issued nexus=7:13:2 -- 1 2002.
Symptoms:
We are noticing SAN errors in our database system (RHEL 6).
Performance on our database server is degraded, Data migration is slow and often timeout.
Cause:
These errors means an error condition being returned from the SAN.
Error message qla2xxx [0000:0c:00.0]-801c:7: Abort command issued nexus=7:10:3 -- 1 2002
qla2xxx is the name of the driver or kernel module.
[0000:0c:00.0] is the PCI bus information of the device.
801c is a hexadecimal id which uniquely identifies the part of the code from where the message originated.
7 is the host number of the scsi target.
Abort command issued nexus=7:10:3 The driver aborted the command that was in progress to the scsi target 7:10:3.
the last 1 means the driver spent time wait for the device to respond.
2002 means the reset succeeded
Resolution:
This messages means there is issues when communication is happening from host 7 related path. The SAN is responding slow,
hence abort messages and communication reset are happening. Please check FC switch logs, FC switch, cabling, zoning or Storage array for possible causes.
If you have Round-robin Multipath Policy enabled, change it to Active/Passive or remove the path(host 7 in this case) till it fixed. So that you can
avoid slowness issues.
