Restart vnxe unisphere webui

Has your unisphere login page got stuck and you cannot login to the unisphere environment to administer your box. There is an ssh command that you can use either through native ssh to the box if you have enabled it through the service options or by attaching the mini serial cable to the unit and using hyperterminal or similar to login to it.

Once logged into the vnxe interface in order to restart the unisphere environment enter the command svc_restart_mgmt and hit enter this will restart the webui which will take several minutes to complete.

This operation only restarts the webui and does not affect the storage in anyway so you can safely perform this action during production hours.

Vnxe write cache temporarily disabled

If you’ve tried to update the vnxe firmware and the update has failed (usually around the 21% mark). Then you will find that the write cache will not be re-enabled until the software update has completed sucessfully. Now when i’ve had this issue emc have stated that its because of a hung process but I found that restarting storage processors do not cure the issue. What I did to resolve the error was to put both storage processors in service mode and then pull the power out of both sp’s. 

Once the vnxe is completely bereft of power the plug both back in and wait for it to boot, take the sps’s out of service mode and re attempt the software update. It should go through without any further issues.

Its essentially the old turn it off and on again solution.

VNXE registration error

When you first switch on a VNXE you have to go through the management network setup tasks, then you have to register the product to download and install the licence file for the software packs you have purchased with the hardware. This is where I hit a bit of a brick wall for a while with our first VNXE 3100. All I got when clicking the obtain licence button was a message on the EMC website saying the Product ID is not recognised. This happened if I type the product ID/ serial number in manually or let the system do it (as it does when you click obtain licence).

So I rang emc support and after a few days of waiting I finally got an answer from them. The support chappie said that it does that if the order company that is registered against the device shows and different to the name of the site so as we bought these from a reseller I guess they were registered under our company name on the order but the site was registered as the reseller.

Quite why this makes any sense I do not know but the support guy emailed the licence files to me and all is now running as it should.
