MDC (md-connect) to an MD

First, find out which MD an AP is on:

(ArubaMM) [mynode] # show ap database | include greenhouse

(ArubaMM) [mynode] # cd cam4

(ArubaMM) [ab:cd:ef:12:34:56] # mdc

Convert CAP to IAP

Campus AP Keeps Rebooting / Upgrade Failed

If a Campus AP keeps rebooting, and its serial console output shows:

SAPD: Reboot after image upgrade failed: 65280

Interrupt the AP boot and execute:

apboot> osinfo Partition 0 does not contain a valid OS image

Partition 1:

   image type: 0
 machine type: 40
         size: 7211308
      version: 6.4.4.0-wave2
 build string: ArubaOS version 6.4.4.0-wave2 for 32x (p4build@cyprus) (gcc version 4.6.3 20120201 (prerelease) (Linaro GCC 4.6-2012.02) ) #49847 SMP Thu Apr 30 14:49:32 PDT 2015
        flags: preserve factory
          oem: aruba

Image is signed; verifying checksum... passed Signer Cert OK Policy Cert OK RSA signature verified.

This means the problem is the old 6.4.4.0 firmware. You need to clear it:

apboot> clear all Checking OS image and flags Invalid image format version: 0x0 Continuing with OS clear 512 bytes written to volume aos0 Erasing flash sector @ 0x3a0000...OK

Device 0: nand0... is now current device Erasing UBIFS ...OK Remove UBI volume ubifs (id 0) Creating dynamic volume ubifs of size 63361024 Device 1: nand1... is now current device

Now tell the AP to boot and it should find mama (the Master):

apboot> boot
