Defect fixes in B.11.31.1003 release
Table 10 B.11.31.1003
DescriptionDefect ID
In the previous release, the IOTreeIndicationProvider polls I/O subsystem frequently to
get the subsystem status. During this polling, the OLAR system call is used internally, which
is an expensive system call and it increases the CPU utilization time.
QXCR1000782615
In the current release, the CPU utilization time (during the subsystem status polling) is
reduced by replacing the OLAR system call by less expensive system calls.
This fix is available as part of B.11.31.1003 release on the AR media, and as a patch
PHSS_40180 for B.11.31.0903 and B.11.31.0809 release.
In the previous release, the IOTreeIndicationProvider polls I/O subsystem, every 1 minute,
to get the subsystem status. During this polling, the OLAR system call is used internally,
which is an expensive system call and it increases the CPU utilization time.
QXCR1000953497
In the current release, users can configure I/O subsystem polling interval to improve the
CPU utilization time. The configuration file, to configure the polling interval, is available
at the following location on the system: /var/opt/iotreeip/config.
By default, the I/O subsystem polling interval value is set to 1 minute.
This fix is available as part of B.11.31.1003 release on the AR media, and as a patch
