855419 - Add Windows 8 support to kittenherder

Status: RESOLVED FIXED

(Infrastructure & Operations Graveyard :: CIDuty, task)

Description

[John Hopkins (:jhopkins)]

Add Windows 8 support to kittenherder, including IPMI reboots.

For testing, use the same limit flag that we use in the buildduty crontab on cruncher, just set the limit string to be the exact hostname you want to test against.

Tested that this patch results in a Windows 8 host reboot via SSH.

IPMI logins are failing because the wrong DNS name is used.

kittenherder transforms this:

 t-w864-ix-062.wintest.releng.scl3.mozilla.com.

into this:

 t-w864-ix-062-mgmt.wintest.releng.scl3.mozilla.com.

(which doesn't resolve)
while Inventory gives an OOB IP which resolves to this:

 t-w864-ix-062-mgmt.inband.releng.scl3.mozilla.com.

[Chris Cooper [:coop] (he/him)]

Should we ask IT to change the DNS, add an alias, or just change the kittenherder code for this slave class?

Comment 5

[John Hopkins (:jhopkins)]

I think we should have kittenherder look in Inventory for the OOB information, since it's available.  I've already started porting some inventory code I wrote to kittenherder.

Comment 6

[John Hopkins (:jhopkins)]

My understanding of the OOB field in Inventory was wrong.  arr says: there are many things that have OOB that do not have IPMI.  If you want to get to the management interface of a machine, use the -mgmt hostname. that will be ilo, ipmi, or whatever the equiv is for that platform.

For example, the VNC interface is often listed in the OOB field.

[12:23pm] jhopkins: we had been doing that, but the -mgmt hostname doesn't [always] have the same domain name
[12:23pm] arr: no, but it always has a bmo CNAME
[12:23pm] arr: so if a person is doing it, use the CNAME
[12:23pm] arr: if a program is doing it, all mgmt interfaces in scl3 are in the inband VLAN
[12:24pm] arr: in scl1 there's a split because it's half new and half old

Attachment: [briar-patch] always use .build.mozilla.org CNAME to look up -mgmt hostname

Using the .build.mozilla.org CNAME is simpler than figuring out the .inband FQDN, so that's what I've done here.  Tested against a stuck w64 host.
