we have a Dell PowerEdge 2950 using a tandberg LTO-4 HH with an Adaptec 29320LPE SCSI Sontroller
ESXi 4.0 works, ESXi 4.1 does not see the naa.id of the tape drive and therefore treats the path to the drive as dead.
Any help would be appreciated if anyone has a solution to this.
We have an open case with VMWARE in which they are submitting this to the developers as a bug issue. We have no resolution yet as of 8/9/2010
At this point we are forced to live with ESXi 4.0 until VMWARE fixes the issue.
Initially we were told by VMWARE support to contact Tandberg which we did. Tandberg support said they do not test their drives on ESX.
VMWARE support then stated that they did not support tape drives and that there was only 1 listed in the HCL for ESX 3.5.
I explained at that point that our option was to switch to another Hypervisor such as Hyper-V or XEN if we could not get the drives to work as we do not have the budget to replace all of the tape drives at our remote locations, or to stand up physcial servers at each of those locations for backups.
Within 2 hours of that conversation, I recieved a call back asking for diags from esxi 4.0.0 and ESXi 4.1 and they would treat this as a bug issue.
As of yet we do not have a resolution and hope to have one soon.
In the mean time if anyone has a fix for this, that would be really helpful.
