Windows 2012 R2 is unable to connect to HP StoreOnce CIFS shares

I ran into this issue the other day with a new HPE StoreOnce deployment. When attempting to connect to a CIFS share on a StoreOnce appliance (it does matter if it is physical appliance or VSA) from a Windows 2012 R2 server, the following error is received “The account is not authorized to log in from this station”.

To fix this, navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters and set RequireSecuritySignature = 0  and then reboot Windows.  When Windows comes back up, you should now be able to browse the CIFS share on the StoreOnce appliance.

HOWTO: Make a 3Par RJ45 serial console cable for an OpenGear ACM5004 Remote Site Manager

On all the 3Par StoreServ 7000/8000 nodes we manage for our clients, we utilize OpenGear ACM5004-F-E Remote Site Manager (basically a serial console switch) so that we can remotely access the serial console on the nodes (in case a node is shutdown to the SMI Whack prompt or something else silly is going on).  The ACM5004 has 4 x RJ45 serial ports on it, which are a Cisco Straight pinout.

Just plugging a standard patch cable into the ACM5004 and the back on the StoreServ node isn’t going to work.  And using the RJ45/DB9 couplers that the 3Par ships with is both a pain in the butt, an eye sore, and bulky.  So I set out to build my own custom RJ45 cable.

On the 3Par end, use pins 2 (orange), pin 3 (blue), and pin 5 (green). Be sure to label this end as the 3Par end!!! I attempt to always put a small tiewrap (which is white in the photo below and hard to see thanks to a blurry photo) around this end of the cable to mark it as the 3Par 3nd.

On the ACM5004 end, use pins 3 (blue), pin 5 (green), and pin 6 (orange). Be sure to label this end as ACM5004!!!

Plug the 3Par end into the node’s serial console port, and the other end into the ACM5004.  After configuring the ACM5004, SSH it and connect the appropriate port on the ACM5004 and you should now see your 3Par serial console.
