[evla-sw-discuss] EVLA Lustre outage tomorrow

[James Robnett]

    We have the new switch for the CBE/telcal to Lustre network
physically in place and mostly wired.

    I'd like to take down Lustre from 11am to noon tomorrow.  We'll
need to move a couple of cables and light up the new interfaces.

    I don't believe I'll need to reboot anything but I will need
the cbe-nodes and mchammer/test to not be accessing Lustre at
the time so can remount the filesystem using the new interfaces.
That will likely require telcal and any CBE I/O threads/shells
to be killed.

    This will not affect AOC NGAS connectivity to the EVLA lustre
install.

    If this time isn't acceptable let me know.  It needs to be
that late to allow travel time and some prep work.
