Topic
An iprutils update that fixes a buffer alignment bug and improves the
performance of supported SSDs is now available.
Description
The iprutils package provides a suite of utilities to manage and configure
SCSI devices supported by the ipr SCSI storage device driver.
This update addresses the following bug and adds the following enhancement:
- a buffer alignment problem prevented iprconfig from updating disk
microcode during I/O. In the block layer, iprconfig incorrectly used
malloc() for memory allocation; as a result, buffers in the scatter/gather
list were not 512-byte aligned. With this update, iprconfig uses
posix_memalign() to properly execute memory allocation, which corrects the
buffer alignment problem. This update also applies several other
improvements to help ensure that iprconfig can perform disk microcode
updates even during heavy I/O. (BZ#452312)
- this update also applies a firmware enhancement to support dual-shared
Active/Active multiplex on SAS adapters. This improves the performance of
supported solid-state disks (SSD). (BZ#475362)
Users of iprutils and the ipr driver are advised to apply this update.
Solution
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
