Unisphere will prompt you to do so as a reminder, however on takeover/failover the newly promoted control station never reboots.īlock Side: Change the sysadmin global domain accountĪ) Updating global domain account passwordġ) Log into Unisphere with the sysadmin global account, using the control station IPĢ) From the “All Systems” page select “Domains”Ĥ) Highlight sysadmin and click on “Modify”ġ) Open a putty session to the primary control station and run the commands below. ![]() Time zone changes needs to be configured separately on each one and is a setting that requires a reboot to take effect. As an example, if the time zone is changed on the active control station it is not part of the synchronization during the failover process. Takeover is initiated by the standby control station, failover is initiated by the active control station. Whenever a change is made to the active Control Station always verify that the standby control station configuration matches on takeover. Please note that Changing the Global VNX administrator password can cause communication failures between the Control Station and the array, the issue is documented in emc261195 and is the reason I’m adding this post, I was researching how to avoid the issue. The article notes that in DART OS versions newer than v7.0.14 the synchronization was automated and the cached credentials are updated automatically, in DART OS v7.0.14 and prior you must do it manually on the active control station. Below is the procedure for changing the passwords on a Unified VNX on both the block and file sides. ![]()
