VxVM vxdmp V-5-3-0 dmp_indirect_ioctl: Ioctl Failed for 23/0x1 with error 22

Problem

After installing VOM5.0 agent, customer may see below dmp error from error report on AIX.  VOM agent uses below command to discover array failover mode:

# vxdmpadm getattr enclosure <controller> failovermode

This error only occured when the array is configured as EMC ALUA.

Error Message

# errpt -a

... 

NOTE VxVM vxdmp V-5-3-0 dmp_indirect_ioctl: Ioctl Failed for 23/0x1 with error 22 

Cause

EMC disk array with ALUA mode only supports "implicit" type of failover-mode.  Moreover such disk array doesn't support set or get failover-mode.  Then any set/get attempts for the failover-mode attribute generate "Ioctl Failed" error messages.

Solution

The error can be ignored safely and would not cause any issue.  You can lower dmp log level like below to avoid the error.

# vxdmpadm settune dmp_log_level=0

 

Or you can apply below HotFix which modified code for set/get failover-mode for EMC ALUA array to avoid error message.

AIX VxVM 6.0.300.5 (Etrack 3236773)

 


Applies To
