| ESXi4.0 Free - upgrade existing datastore (HD) I have this running on a DELL PE 2900 with a 6ir sas raid controller however I'm not using raid but JBOD. I have 8 assorted physical drives, datastores 0-7. My problem is matching the datastore to a physical drive in the 2900.
Help appreciated. |

kudos:4 | Are the drives all the same size? I suspect not cause that would be easy to match them up, or at least some of them. There is an identifier but I'm not sure how to match it up to physical drives. Someone with linux skill could probably tell you how to match it up. Might need the vSphere MA to get you the CLI access you need, tho SSH might be able to do it as well. I'm still a bit new to ESXi but I do run 4 servers on 2 2950 III's, one 2850 and a Precision 690.
Out of curiosity, why don't you run the drives in a raid mode? |

At the time I started this project I had zero budget and not enough "large size" drives. Also, the VM's I create are used for testing a specific software app. on many different OS's and it is very disk i/o intensive, so I went with single drives in order to minimize the i/o overhead associated with sharing raid volumes.
Thanks. |

kudos:4 | That's a good way of keeping heavy I/O loads isolated to one app, that one app doesn't drag down the others. I've been googling for the solution and it looks like there is but it will only provide you the info if the SCSI controller passes along the raw device info (such as for monitoring drive health). Also it requires running a script and that's getting in over my head at that point. See here for what I think is the solution: »communities.vmware.com/thread/199287. It appears there's a function call you can use but I'm really not sure at this point. |
