A quick note on an issue I spotted in VMware vSphere 6.5 when creating a new content Library. If the datastore being used for the new library contains a space in it’s name then the Create Content Library process fails. The error given is “The specified parameter was not correct: The provided storage backing xxxxx xx for library xxxxx-xxxx-xxxx-xxx is invalid.”. For example, if a second vSAN cluster has been created and the default name “vsanDatastore (1)” was used for the datastore.
Rename the target datastore to a name which does not contain a space then repeat the Content Library creation process.
This occurred in my environment running vSphere 6.5 (vCenter VCSA build 18.104.22.16800) and hasn’t been thoroughly tested for repeatability (at least by me).
When setting up a new vRealize Operations 6.6 environment (using the vRealize Operations Manager Initial Setup wizard) the password is not accepted despite apparently meeting the complexity requirements.
The criteria stated are that passwords must:
- Be at least eight characters long
- Be different from your username
- Contain lowercase, uppercase, numeric, and non-alphanumeric characters
It appears that full stop and question mark do not count as the “non-alphanumeric” characters required.
Choose another password which includes a different, acceptable, non-alphanumeric character such as the exclamation mark.

When using a GoPro Session Action camera it’s important to ensure that an approved MicroSD card is used. As this short video demonstrates, this really makes a difference to the performance. Two 32GB SanDisk MicroSD Cards, the first is the “Ultra” brand and the second the “Extreme” model which is listed on the approved card list. With the “Ultra” card it takes 30 seconds from the button being pressed to the camera starting to record. This is cut to just 2 seconds when using the “Extreme” card. Continue reading
With a list of Surnames in a text file I wanted to see how many start with A, how many with B, and so on. This is my PowerShell solution:
