Tips for successfully installing an Ultra DAC on Series 5 Gear

[Anonymous]

In this article I will share a tip to help ensure the successful installation of an Ultra DAC on Series 5 Hardware. During a customer install we ran into a situation where after cabling up the Ultra DAC to a Series 5 Packet Decoder and booting up we encountered some strange output from the nwraidutil.pl command. The first 30 drives of the Ultra DAC were displaying a strange N/A where the enclosure number should be (See example below in RED). For some strange reason the PERC 830 Adapter was only recognizing ½ of the enclosures drives. We continued to get this result even after rebooting the appliance.

The solution is to POWER OFF the appliance. For some reason the PERC 830 adapter isn’t power cycling during a normal reboot. If you have physical access to the appliance, power it off for 15-30 seconds. Power it back on, let it boot, and re-run the nwraidutil.pl command and you should now have a number assigned for the first 30 drives in the enclosure. If you do not have physical access but do have iDRAC connectivity perform a cold boot / power off, wait 15-30 seconds, power on, etc…

DO NOT run the NwArrayConfig script if you are seeing N/A in the Encl section. This will result in you having to perform manual de-configuration on the DAC.

Also it might be helpful to use the NwArrayConfig script located in /opt/rsa/saTools with one caveat, DO NOT use any version of this script than;

rsa-sa-tools-10.6.1.1-118.4.eb0e5a2.el6.noarch.rpm‌

***Please reference this Article for details…

Good stuff. I haven't had the opportunity to configure one of these yet and will definitely keep this in mind when I have to.
