 ERROR DESCRIPTION:
 Due to OSA firmware changes with the z14, a Delete IP Multicast
 (DELIPM) request may fail with a return code of x'200B'.
 This request is issued by a VSWITCH controller for a Layer 3
 (IP) vswitch.
 LOCAL FIX:
 
 PROBLEM SUMMARY:
 ****************************************************************
 * USERS AFFECTED: All users of OSD devices and VSwitch IP      *
 *                 (Layer 3) Uplink devices                     *
 ****************************************************************
 * PROBLEM DESCRIPTION:                                         *
 ****************************************************************
 * RECOMMENDATION: APPLY PTF                                    *
 ****************************************************************
 When a Delete IP Multicast (DELIPM) request to an OSD device
 fails, the stack treated this as a fatal condition and took
 the device down, causing it to go into AUTORESTART
 processing.  If the device was a VSwitch Uplink device, the
 VSwitch goes into recovery mode and may choose an alternate
 primary device. Such a failing request should not be treated
 as a fatal condition, but instead a message will be written
 to the console.
 PROBLEM CONCLUSION:
 TCTOOSD has been updated when receiving an error on a Delete IP
 Multicast (DELIPM) to allow the device to stay up, and write a
 message to the console.
 
 CP APAR VM66216 should be applied in addition to this APAR.
