bug in VMHostStorageInfoImpl.ScsiLun.SerialNumber?

[halr9000]

(this was already reported privately to c_shanklin, posting here for others' benefit)

For some reason the serial #'s are not being populated below.

PS > Get-VMHost | Get-VMHostStorage | select -ExpandProperty ScsiLun | select Vendor, Model, SerialNumber

I'm not sure this is a VITK bug.

In the ScsiLun object the serialNumber property also returns "unavailable" for my iSCSI LUNs.

In the SDK reference it says "The serial number of the SCSI device. For a device that is SCSI-3 compliant, this property is derived from page 80h of the Vital Product Data (VPD), as defined by the SCSI-3 Primary Commands (SPC-3) spec. Not all SCSI-3 compliant devices provide this information. For devices that are not SCSI-3 compliant, this property is not defined."

That makes a lot of sense. I would ask VMware to consider having the VITK return $null instead of "undefined", as that is consistent with other powershell conventions. But otherwise, now that I know what to expect I can safely document it thusly in my book.

I would appreciate if anybody has some fancy SCSI-3 drives try this out and paste the output.

Just checked my very fancy IBM Bladecenter--still says unavailable.
