Db2 Version 11.1 Mod 4 Fix Pack 6 for Linux, UNIX, and Windows
Db2 Version 11.1 Mod 4 Fix Pack 6 for Linux, UNIX, and Windows

APAR status

• Closed as program error.

Error description

• GPFS team has published a technote outlining the steps required
  to properly shutdown and restart gpfs daemons -
  https://www.ibm.com/support/pages/node/6118084
  
  This fixes some 'unable to unload kernel module' issues that
  remain persistent even after reboot.
  As per this, we will need to change our 'enter maintenance'
  procedure in Db2 as well.
  

Local fix

• there are options to rename the module that is not being
  unloaded by the kernel; however, these must be done and verified
  in conjunction with GPFS support only.
