Resizing ISE VM

virtualpedia — Fri, 11 Sep 2020 19:06:30 GMT

I have a question in regards to modifying the ISE VM. If you have a small VM license, can you increase the disk size prior to initial power on, after deploying the OVA, or does that break license?

For example, small VM shows 600GB, prior to initial power on, can you change it to 800GB?

You can expand the disk, however ISE will not take advantage of it. You need to reinstall the application/VM from the ISO in order to take advantage of the additional disk space. The small VM license is based on the CPU and memory assigned the node, you can have any disk size you want up to around 2TB.

You have two supported options to increase the disk space, but both require the ISO.

1. Deploy the OVA, increase the disk to 800 GB, mount the ISO, boot from the ISO and reinstall.

2. Deploy the VM straight from ISO, building your own VM template. This is OK if you know the exact cpu/disk settings for a small VM already.

If you adjust the disk at any point from 600 to 800 without the reinstall from the ISO, then ISE will only ever see the original 600.
