I was just testing Replicate Datacenter Analyzer(RDA) 1.2 at a customer site. Well “testing” might not be the correct word in this case. RDA 1.2 discovered several things which are impossible to discover manually when you’ve got 5+ hosts.

Vimsh solves this: /usr/bin/vmware-vim-cmd [...]

I was talking to a fellow consultant today. He ran into the following error messages at one of his customer sites: vmkernel: 8:18:59:58.640 cpu2:1410)WARNING: Heap: 1370: Heap_Align(vmfs3, 4096/4096 bytes, 4 align) failed. caller: 0x8fdbd0 vmkernel: 8:18:59:58.640 cpu2:1410)WARNING: Heap: 1266: Heap vmfs3: Maximum allowed growth (24) too small for size (8192) During the conversation I knew I’d seen this problem before.

Selecting the appropriate storage model is important for both [...]
