SCI-54360

SR# 17429919

In systems with over 2000 devices, the VxFlex OS GUI and Gateway might not receive some device objects, causing the GUI to not display those devices, and the Gateway and GUI to falsely send an alert for the Storage Pool not meeting the minimum number (3) of fault units.
SCI-54185 During NDU from v2.x to v3.x, in systems with thousands of VTrees, the MDM may crash several times in the upgrade post-processing phase (after all SDSs were upgraded and before the finalize_upgrade command is allowed).
SCI-54083

SR# 17693786

Initiation of log collection using the VxFlex OS Gateway fails.
SCI-53961 The command drv_cfg --query_block_device_id does not work on AIX-based SDCs.
SCI-53895 While upgrading a system with Windows SDC using the Installer, upgrade of LIA might fail.
SCI-53615 Following a user password change, inactive GUI sessions might generate a large amount of failed login retries.

SCI-53105

SR# 17312708

When using Java 8u241, MDM and LIA certificates have to be re-approved upon every VxFlex OS Gateway restart.
SCI-52513 When using the command sg_dd to test I/O to /dev/sciniX devices, the server might crash.
SCI-52479 On Windows operating systems, after removing the VxFlex OS Gateway using Add\Remove Programs, a new VxFlex OS Gateway cannot be installed. This happens because the VxFlex OS Gateway service was not removed. In many cases, this is caused by not performing a reboot prior to a new installation.
SCI-52368

SR# 17017018

In large scale systems with a large number of SDCs, the following message may fill up the log files: multiheadRow_InitiateRoleSwitchIfNeeded

Example of full message:

SCI-52147

SR# 16933891

AMS mistakenly reports "Errors have been detected on the Physical Disk" on drives from slots 0 and 1 in all nodes. The issue is caused due to a text change in iDRAC 4.00.00.00 that causes sampling to raise a false alert.

grep: write error: Broken pipe

SCI-52036

SR# 16858218

The command enter_maintenance_mode may take longer than expected, sometimes resulting in an MDM crash, after which MM entrance will continue normally. This has a higher chance of happening during NDU from v2.x to v3.x.
