An updated iprutils package that fixes various bugs and provides one enhancement is now available for Red Hat Enterprise Linux 6.
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
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.
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.
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.
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.
All users of iprutils are advised to upgrade to this updated package, which fixes these bugs and provides this enhancement.
