52575 Virtual volume and logical disk
ownership may not be properly
rebalanced after InFormOS
upgrade.
During InForm OS upgrades, nodes are
shutdown to be rebooted. The InForm
OS is designed to properly rebalance
virtual volume and logical disk
ownership after reboots. When the
system is under heavy loads, the
rebalancing process may fail due to
lack of system resources which can
cause an unbalanced load in system.
A fix was implemented to change
resource allocation so there are more
resources available for rebalancing.
After a failure of the initial
rebalancing attempt, the retry
frequency has been increased from
once every hour to once every 15
minutes.
52853 Assertion failure on non-RTPG
maint-in command.
Under certain conditions,
maintenance commands which were
not reported target port group
commands were asserting in the RTPG
handler.
The check has been improved to
handle these cases.
