FS#4439 — Maintenance infra network- 06/08/10
Scheduled Maintenance Report for Web Cloud
Completed
We are launching a maintenance on the shared infra network on 06/08 at 01:00 CEST (estimated duration: around 1h). The shared hosting's plate-form would be unavailable during a maintenance of few minutes (around 4 to 5 min).


Update(s):

Date: 2010-08-07 23:18:43 UTC
End of maintenance for tonight. we are planning ASAP a new nightly intervention for p19-61/62.


Date: 2010-08-07 23:16:35 UTC
We tried with the 2nd fex 2248, the same.

However, after checking, problems were prior to these ports and the machines have already been moved to other ports of the same fex. This will give us time to solve the problem on the fex 2248.



Date: 2010-08-07 23:14:19 UTC
We resolved the uplinks problems on 2248 but the fex is not mounting:

p19-66-n5# 2010 Aug 6 03:21:54 p19-66-n5 %$ VDC-1 %$ %VMM-2-VMM_SERVICE_ERR: VDC1: Service SAP 175 returned error 0x40290000 (err
or) in if_bind sequence

Date: 2010-08-07 23:12:53 UTC
The couple p19-65/66 is actually updated but the fexs passed off-line after rebooting p19-65 on the latest version and reactivation of ports-channels.
At this moment, for an unknown reason, fex's port configuration was reinitialised at part of p19-65 which is provoking a mismatch between the configuration of the 2 chassis. Even by disconnecting the uplinks of the fexs at part of p19-65, ports are not remounted on p19-66. We decreased the configuration of all fex ports on p19-65 and ports are remounted.
We must review the migration protocol for p19-61/62 which contains 6 fexs. We are reporting then, the upgrades on these switches to a later date.

We are facing difficulties to remount fex 2248.


Date: 2010-08-07 23:02:04 UTC
Upgrading p19-65 is now in progress.

Date: 2010-08-07 23:01:27 UTC
Correction, p19-66 is upgraded. We are reloading the fex on this chassis.



Date: 2010-08-07 23:00:12 UTC
Upgrading p19-65 in progress.

Date: 2010-08-07 22:59:29 UTC
Reload on the same version p19-66 because of a bug in progress. We could then start the upgrade itself.


Date: 2010-08-07 22:56:42 UTC
thereafter a cisco bug blocking the upgrade ( Inconsistent error message comparing to the available place on the bootflash), we restarted p19-65 (on the same version). After this reboot, 7 ports among one of the fex is set to error. A fex spare 2248 is ready to start on this couple of chassis. We have to finish the upgrade of the peer in order to upload it (2248 is not supported but in the latest version of nx-os).

error message:
Version Compatibility check failed. Return code 0x40930062 (free space in the filesystem is below threshold).

Date: 2010-08-07 22:48:28 UTC
we are starting the task. Switches p19-61/62 and p19-65/66 are going to restart successively to be updated.
