PRVE-10167 : I/O Completion Ports (IOCP) device status did not match the required value on node "nod

APPLIES TO:

Oracle Database - Enterprise Edition - Version 12.1.0.2 to 12.1.0.2 [Release 12.1]
Information in this document applies to any platform.

SYMPTOMS

Grid Infrastructure CVU reports the following warning:

PRVE-10167 : I/O Completion Ports (IOCP) device status did not match the required value on node "isdprod11adm". [Expected = "Available"; Found = ""]

Check for I/O Completion Ports (IOCP) device status failed

 

SOLUTION

Case 1: IOCP is not configured properly on OS level:

# lsdev -c iocp

iocp0 Defined I/O Completion Ports
The status needs to be "Available" instead of "Defined", the following error will be reported later if IOCP isn't configured properly: 

exec(): 0509-036 Cannot load program sqlplus because of the following errors:

rtld: 0712-001 Symbol CreateIoCompletionPort was referenced

from module /ocw/c102/lib/libttsh12.so(), but a runtime definition

of the symbol was not found.

rtld: 0712-001 Symbol GetMultipleCompletionStatus was referenced

from module /ocw/c102/lib/libttsh12.so(), but a runtime definition

of the symbol was not found.

rtld: 0712-002 fatal error: exiting.
Engage SysAdmin to configure it properly.
 

Case 2: IOCP is configured properly on OS level

# lsdev -c iocp

iocp0 Available I/O Completion Ports
CVU trace shows "/etc/lsdev" is used

Output: '<CV_CMD>/tmp/CVU_12.1.0.2.0_grid/checkIOCPDeviceStatus.sh </CV_CMD><CV_VAL>/tmp/CVU_12.1.0.2.0_grid/checkIOCPDeviceStatus.sh[34]: /etc/lsdev: not found <RESULT>VFAIL</RESULT>
The bug is fixed in 12.2:
BUG 20225311 - PRVE-10167 : I/O COMPLETION PORTS (IOCP) [EXPECTED = "AVAILABLE"; FOUND = ""] 
As lsdev command confirms the device is "Available", it can be temporarily ignore.
