ulsfo possible downtime - PDU swaps in both cabinets
Closed, ResolvedPublic

Description

In the investigation on T119631, @RobH opened a ticket to investigate temperature issues. During UnitedLayers investigation, it was discovered that one of the NICs in each cabinet's PDUs is malfunctioning. Email from UL Support quoted below:

It has come to our attention that your network management card for your
(b-side)PDU in cabinet 1.23 and (a-side) PDU in cabinet 1.22 is
malfunctioning. We are not able to remotely access and monitor your PDU
because of this issue. We would like to work with you to fix the issue sooner
than later so we do not run into any problems.
There may be some downtime with a few of your servers associated with this
work so we would like to schedule a maintenance window to your convenience so
that we can go ahead and swap out the bad PDU. If we determine that downtime
is needed, we can schedule this maintenance window during off hours so the
impact to your business continuity is at a minimum.
Please let me know if you have any questions or concerns. If you would like to
discuss this over the phone please let me know and I can accommodate this for
you.

We will need to coordinate a downtime window. All the systems (except the mgmt switches and mr1-ulsfo) have redundant power supplies, and should remain online during this PDU replacement.

Systems without redundant power: mr1-ulsfo, msw1-ulsfo, msw2-ulsfo, altas-ulsfo, scs-ulsfo.

Downtime has been confirmed for 2016-02-17 1800-2200 GMT.

For ulsfo user-facing traffic, the lowest point of the day is approximately a symmetrical dip centered on 20:00 UTC (Noon Pacific). So if they need a 4-hour window, ask for 10AM -> 2PM their time, etc. Given weekend risks and all of that in general, I'd prefer we do this mid-week (Tues, Weds, or Thurs).

And to be clear, what I expect we'll do on our end is depool ulsfo from users in DNS in our config-geo ahead of the window (let's say 2 hours ahead? the TTLs are 10 minutes, but there's always stragglers), and bring them back after they're done. Assuming we don't actually lose the machines or network and purges keep flowing throughout, there's no need to wipe any caches before repooling, either.

Re: [UnitedLayer #118704] SF8 - Wikimedia: PDU nic failure

Phu/Support,
We prefer the PDU swap happen during our traffic low-point at that site,
which is 20:00 GMT / 12:00 Pacific. So for a maintenance window, can we
set it for the two hours before and afterwards, so 10AM to 2PM Pacific;
additionally we would like to keep this work to Tuesday, Wednesday, or
Thursday.
Please let us know which of the upcoming Tuesday/Wednesday/Thursdays
between 10:00-14:00 Pacific work best for you. All but our management
network have redundant power supplies wired to both towers, so actual
downtime should be minimal. We plan to migrate all traffic away from that
site during the maintenance window as a preventative measure.
Please advise,

We cannot see any power from the new PDU in 1.23, as our mr1-ulsfo (Juniper
SRX100B in U36 of 1.23) hasn't powered back up. If these new PDUs are
switch outlets, might the outlets not be turned on?
We cannot see any of our mgmt interfaces to check power use, as the

Please advise if you are able to connect a power meter and read power

Re: [UnitedLayer #118704] SF8 - Wikimedia: PDU nic failure

Support,
I still dont see power output to both of our power supplies on our router,
which leads me to think we still don't have power output to all ports.
Additionally, the mr1-ulsfo management router that I advised on in my last
email is still not powered on, nor does there seem to be power to
msw1-ulsfo, a switch in that rack.
Can you confirm with a multi-meter reading that there is power output on
the outlets? (This was already requested, but was not yet addressed.)

We cannot see any power from the new PDU in 1.23, as our mr1-ulsfo

(Juniper

SRX100B in U36 of 1.23) hasn't powered back up. If these new PDUs are
switch outlets, might the outlets not be turned on?
We cannot see any of our mgmt interfaces to check power use, as the
mr1-ulsfo and the mgmt switches are powered down in 1.23 due to being in
the offline PDU.
Please advise if you are able to connect a power meter and read power
output on any of the outlets in the replacement PDU in 1.23?

Re: [UnitedLayer #118704] SF8 - Wikimedia: PDU nic failure

Carlos,
I'm now trying to connect to other devices, and it seems that I cannot
connect to the mgmt network yet. I see power to both the power supplies on
our main routers(MX480s), but the others seem to be taking time to come
back online.
Can you advise if the switch labeled msw1-ulsfo (1.23:u38 or
msw2-ulsfo)(1.22:u37) have powered on? mr1-ulsfo also hasn't come back
online yet, and its been long enough that it should have booted by now.
Unfortunately, with those down I cannot troubleshoot, as they are my mgmt
network. You advised mr1-ulsfo was powering on correct? Does it have any
error indicator LEDs illuminated? We've left the end of our downtime
window, so I'd like to try to resolve this before the evening.
Please advise,

Additionally, the mr1-ulsfo management router that I advised on in my

Can you confirm with a multi-meter reading that there is power output

Re: [UnitedLayer #118704] SF8 - Wikimedia: PDU nic failure

Actually, if whoever is on the floor troubleshooting can call me back
directly on my cell I'd be happy to stay online with them while we
troubleshoot all the devices that are offline. Carlos called me earlier
with an update, but after we got the update I hung up to check the
devices. My cell is 727-255-4597.
When this was originally scheduled, I hadn't planned on being onsite. If
we cannot get this sorted shortly, I'll head down there to work with
UnitedLayer directly. We would prefer to avoid downtime during the peak

Re: [UnitedLayer #118704] SF8 - Wikimedia: PDU nic failure

Hi Rob,
Let me take a look and will call you back with my findings.
--Carlos

Carlos,

20

I'm now trying to connect to other devices, and it seems that I cannot
connect to the mgmt network yet. I see power to both the power supplies =

on

our main routers(MX480s), but the others seem to be taking time to come
back online.

20

Can you advise if the switch labeled msw1-ulsfo (1.23:u38 or
msw2-ulsfo)(1.22:u37) have powered on? mr1-ulsfo also hasn't come back
online yet, and its been long enough that it should have booted by now.

20

Unfortunately, with those down I cannot troubleshoot, as they are my mgmt
network. You advised mr1-ulsfo was powering on correct? Does it have any
error indicator LEDs illuminated? We've left the end of our downtime
window, so I'd like to try to resolve this before the evening.

20

Please advise,

20

Re: [UnitedLayer #118704] SF8 - Wikimedia: PDU nic failure

Carlos/Support,
Per our phone call just now, it seemed it all was working except
mr1-ulsfo. The hard reboot we had just done didn't seem to work; however,
right after we hung up, it came back online.
It appears that all our devices have nominal power and are working. Please
advise when UnitedLayer has locked up the cabinets (and all work/cleanup is
complete) and we'll repool our services there.
Thanks!

Re: [UnitedLayer #118704] SF8 - Wikimedia: PDU nic failure

Hi Rob,
All work has been completed. We have successfully replaced the pdu and clos=
ed
up your cabinet. Let us know if you require any other assistance.

Carlos/Support,

Per our phone call just now, it seemed it all was working except
mr1-ulsfo. The hard reboot we had just done didn't seem to work; however,
right after we hung up, it came back online.

20

It appears that all our devices have nominal power and are working. Plea=

se

advise when UnitedLayer has locked up the cabinets (and all work/cleanup =

is

complete) and we'll repool our services there.

20

Thanks!

Can you advise if the switch labeled msw1-ulsfo (1.23:u38 or
msw2-ulsfo)(1.22:u37) have powered on? mr1-ulsfo also hasn't come ba=

online yet, and its been long enough that it should have booted by no=

Unfortunately, with those down I cannot troubleshoot, as they are my =

any

error indicator LEDs illuminated? We've left the end of our downtime
window, so I'd like to try to resolve this before the evening.
Please advise,

Hi Rod,
The power cable from your firewall to the pdu was a bit loose. I

it

properly and it came back up.

I still dont see power output to both of our power supplies on =

router,

which leads me to think we still don't have power output to all

Additionally, the mr1-ulsfo management router that I advised on=

msw1-ulsfo, a switch in that rack.
Can you confirm with a multi-meter reading that there is power

the outlets? (This was already requested, but was not yet

addressed.)

Support,
We cannot see any power from the new PDU in 1.23, as our

mr1-ulsfo

(Juniper

SRX100B in U36 of 1.23) hasn't powered back up. If these new

PDUs

are

switch outlets, might the outlets not be turned on?
We cannot see any of our mgmt interfaces to check power use,=

the

mr1-ulsfo and the mgmt switches are powered down in 1.23 due=

Please advise if you are able to connect a power meter and r=

power
