Re: can we disable and enable the slot in DCX switch

You did not offer much detail on what slot and why you wish to disable/enable a blade  in the DCX.

That said, it is possible to disable/enable each slot in the DCX using commands: slotpoweroff / slotpoweron.

 

The commands are explained in the FOS Command Reference Guide.

 

Example:      switch: admin> slotpoweroff 3     <--powers down slot 3

                       switch: admin> slotpoweron 3    <-- powers on slot 3

 

As a side note, if you power off a core blade it will reduce the DCX's switching capacity by 50%, and all i/o traversing

DCX fc blades will be forced through the surviving core blade.  Powering down a core blade is suggested to be

done during off-peak i/o hours.

Right, but this requires a non-documented option...

You can also use ranges to disable/enable multiple ports in one command, but the ports will be disabled/enabled one-by-one at appx. 2-3 ports per second in fact, not all at the same moment.

[ Edited ]

It will depend on the FOS level as to whether slotpoweroff requires additional syntax.

I dont know when Brocade change things but below is a DCX with 2 core operating blades

running v7.4.1d.  I can power down core blade in slot 3 by simply using the "slotpoweroff 3" command. 

No added syntax required.

You have chosen a core blade to power off, if this is the last operational core blade then the chassis will disable itself.
Would you like to proceed? (yes, y, no, n): [no]y

 

Slot 3 is being powered off
