16 Resolved Issues
Issue ID Functional Area Description
MDT-231279 Hardware Upon issuing managed shutdown to one of the storage controllers, in rare cases
the unmanaged shutdown (reboot) might occur instead.
MDT-247447 Hardware In some cases of node reboot due to kernel panic we are unable to root cause the
issue because the kernel dump does not complete in time allowed. This is because
we prioritized fast reboot over diagnosable materials. Timing of this process is
under review.
MDT-272231 Hardware Cluster cannot add two new appliances "The system encountered unexpected
backend errors."
MDT-253764 Hardware SYM to fix sym_mom_is_ssd_fru_state_ok so it will check that all healthy PMs
sees the drive as OK.
SYM will not accept a new drive to DP before it is up on all healthy nodes.
MDT-237899 Hardware While performing HA testing customer issued command to reboot node_a
multiple times, this indeed triggered reboot of node_a and then node_b reboot
causing outage.
When reboot was initiated for a second time, the command was issued to the
second node which has CP as the failover which completed from first reboot
request and thus triggered reboot of second node in addition to first node reboot.
MDT-241178 Hardware The access control account for the certificate created on primary node failed to
sync with member nodes in the cluster due to synchronization framework failure
because of the underlying OS signals. As a result, when failover happens, the
certificate account will not be on the newly elected primary node and the
corresponding application will report the missing cert account. The
synchronization failure is mitigated and fixed in this release.
MDT-194839 Hardware During NDU, in rare cases the upgrade is stopped and drive failure tiers are left in
a degraded mode while the system continues to service I/Os.
MDT-233808 Hardware Rare race condition on system boot between iSCSI portal configuration and ESXi
iSCSI adapter rescan.
MDT-252811 Hardware PSU is not marked as disconnected state when its sensors don’t get updated in OS.
MDT-232303 Hardware After adding drives and restarting SYM, sometimes CLST didn't rebuild SSD group.
In that case if adding drives to the point that the user added more than half of the
total new drives - there might be a possible loss of majority.
This causes SYM not being able to restart
MDT-260065 Hardware BBU is marked as disconnected state when its sensors don’t get updated in OS.
