But I believe you will think about that SFP Module itself is not functioning properly or your Device Port is not functional at first time experience. Well...it is not. Your Cisco Device will prompt you with below Log Message in the console. %PHY-4-UNSUPPORTED_TRANSCEIVER: Unsupported transceiver found in Gi1/0/52 %GBIC_SECURITY_CRYPT-4-VN_DATA_CRC_ERROR: GBIC in port 65538 has bad crc This log message says that the port attached with third party SFP Module just disabled. So, we need to workaround to work that. Just need to type two commane line as below, switch>configure terminal switch(config)# service unsupported-transceiver switch(config)# no errdisable detect cause gbic-invalid You should see Warning Message after you key-in "service unsupported-transceiver " that prompt Cisco Warranty will not cover if you use Third Party SFP Module. no errdis

I've got 16 ESXi Server. New 9 ESXi Servers (5 for Server Cluster and 4 for Workstation Cluster) running as production currently. Old 7 ESXi Servers (5 for Server Cluster and 2 for Workstation Cluster) and Workstation Cluster is running as production currently. Server Cluster is for backup purpose. One day I've to remove for 5 ESXi Servers of Server Cluster to make free space of Server Rack for new server increment setup. But the problem is those old 7 ESXi Servers are located on two rack and some more is two servers from two clusters are located on separate RACK. So, I've got to move those server to be in same rack and same cluster. Below are my experience of moving VMs and Host between clusters for reference for who might encounter like me. Moving host got two method. 1) moving vms from that host and moving the intended host from cluster to cluster by drag and drop with maintenance mode. 2) moving vms from that host and disconnect it from current cluster and

Once I've migrate my vSphere 4 to 5, I got need to change some Server NIC from E1000 to VMXNET3 as they are not touched while migrating to avoid unnecessary issue and delay in project period. But after migrated, I start noticed that some server like File Server, SAP or other server those need high user access definitely need to convert to VMXNET3 to get better performance. So, I've decided to convert and follow is my steps in converting process. That will be the easy guide for you too. Actually, you will see two method to covert the adapter type. - Shutdown the server and add new NIC. Uninstall old NIC and update NIC setting of old to New. - Using VMware PowerCLI for live converting without touching server. Here, I'm using second method, PowerCLI, to make conversion. You need to download and install the VMware PowerCLI into your machine before start. OK. Let's start now. -          Check the Network Adapter Type and Adapter Number 1 or
