RHEA-2011:1546 - Product Enhancement Advisory

Topic

An updated iprutils package that fixes various bugs and provides one enhancement
is now available for Red Hat Enterprise Linux 6.

Description

The iprutils package provides utilities to manage and configure SCSI devices
that are supported by the IBM Power RAID SCSI storage device driver.

The iprutils package has been upgraded to upstream version 2.3.4, which provides
support for the Serial Attached SCSI (SAS) vRAID functions. (BZ#693816)

This update fixes the following bugs:

• Due to a NULL pointer dereference, the iprconfig utility terminated

unexpectedly with a segmentation fault when attempting to display hardware
status. A patch has been applied to address this issue and hardware status is
now displayed correctly. (BZ#694756)

• Previously, iprutils did not work correctly when performing RAID migration and

asymmetric access functions on new adapters. With this update, array migration
functionality is fixed. Now, iprutils can correctly perform the raid migration
and asymmetric access functions. (BZ#703255)

• The find_multipath_vset routine used the ARRAY_SIZE() macro to calculate the

length of the serial number. Previously, the length was calculated incorrectly,
which could have led to false positives when looking for the corresponding vset.
As a consequence, attempting to delete arrays failed: the target and the second
array were set to be read/write protected, writing to both arrays was not
possible, and the system had to be rebooted. To fix the problem, the
IPR_SERIAL_NUM_LEN macro is now used instead of ARRAY_SIZE. (BZ#741835)

• With the maximum number of devices attached to one of the new Silicon

Integrated Systems (SiS) 64-bit adapters, the configuration data could have
grown over the buffer size. With this update, the buffer size has been
increased, which fixes the problem and ensures room for any possible future
growth. (BZ#741835)

All users of iprutils are advised to upgrade to this updated package, which
fixes these bugs and provides this enhancement.
