What'sJohnWorkingOn

I needed to replace a drive reported for predictive failure on a Dell 730xd so I ran:

racadm raid replacephysicaldisk:Disk.Bay.3:Enclosure.Internal.0-1:RAID.Integrated.1-1 -dstpd Disk.Bay.10:Enclosure.Internal.0-1:RAID.Integrated.1-1

This will replace a disk in your virtual disk, but won’t update the iDRAC display until the iDRAC is reset, or the machine rebooted.  You can verify the job is finished with the lifecycle log, or by using the percli tool to view the topology before doing the reset.

perccli /c0 show

You can get the tool here:

You can reset the iDRAC from racadm:

I got the following error after I finished a cut.  The problem was that the z-axis had gone too far done, and when it powered up it was already in contact with the z-axis switch.

To fix it, I had to remove the side panel on the side that contains the control panel and adjust the wheel that controlled the z-axis screw, moving the platform up manually.  Doing that allowed the cutter to resume normal operation. 

I had been asked to create a one-button solution to dial a videoconference on a polycom group series.  The unit was on a mobile cart and did not have a fixed IP.

I used the Polycom Intergrator Manual to get the API command needed:

dial addressbook name

Where name is the unique first name of an entry in the address book. I needed to create a serial connection from the button to the polycom serial cable (part number 2457-63542-001) .  I first tried an arduino with a  MAX3232C transceiver and DB9 connector, but it could not send the signal required.  I switched to a raspberry pi instead and a FTDI usb to serial adapter which worked correctly.
