When I try to FTP some files using an interface, the speed is unexpectedly slow. Then I try to see the network interfaces status:
root@sunserver # dladm show-dev
nxge0 link: down speed: 0 Mbps duplex: unknown
nxge1 link: down speed: 0 Mbps duplex: unknown
nxge2 link: unknown speed: 0 Mbps duplex: unknown
nxge3 link: unknown speed: 0 Mbps duplex: unknown
igb0 link: up speed: 100 Mbps duplex: half
igb1 link: unknown speed: 0 Mbps duplex: half
igb2 link: up speed: 100 Mbps duplex: full
igb3 link: up speed: 1000 Mbps duplex: full
Seems 100 Half is a wrong setting. Since the speed is set by auto negotiation mode, we have to change it manually:
First, check the interface properties by "ndd":
root@sunserver # ndd -get /dev/igb0 ?

My current job needs to take care of some EMC storages, from DMX to VMAX (also some Clariion/VNX and Celerra). Since I forget all the symcli commands, I created the following tables for quick reference (the table will be updated time to time...) :

ITM product code
Recently I am doing projects related to IBM Tivoli products. One of them is the IBM Tivoli Montoring (ITM). To check which products are installed and running. There is a tool "cinfo", but it only shows the product code, which is not very meaningful.
Therefore I try to search a product code list for reference:
