Abstract

VIOS (Doc Number=6773): High Impact / Highly Pervasive APAR IJ30090

Content

IJ30090 - Tape backup or restore may fail or be slow with VIOS 3.1.2 using NPIV

LPARs running applications with serialized I/O (typically tape jobs) using Virtual Fiber Channel adapters (NPIV) on VIOS 3.1.2 may experience slow I/O or I/O failures.

We have seen this primarily with IBMi tape backups over NPIV, causing them to take significantly longer or fail after updating the VIOS to 3.1.2.
