Hi,
We have just tried to upgrade a networks of mixed cluster IAP's to the latest version. As the customer has a mixed cluster of IAP we used TFTP.
All of the IAP-115's upgraded but the IAP-105's didn't upgrade and went missing from the VC. We tried to SSH onto the slave 105's to try to make them upgrade but they wouldn't. I used the command below
upgrade-image tftp://172.27.196.42/ArubaInstant_Orion_6.4.4.6-4.2.4.0_55341
After issuing the command I watched the TFTP server but the IAP-105 didn't try to upgrade.
In the end we had to remove every IAP-105 (10) from the network and put them on an isolated staging network away from the existing cluster and then upgrade them manually to the same level as firmware as the IAP-115's. When they were connected back the orignal network they rejoined the cluster and worked.
Becasue of the location of the IAP-105 this process took hours.
If there an easier way of upgrading the formware slave IAP's if they fail to upgrade?
