Why is My Pegasus3 SSD Volume Taking so Long to Format?

2018-02-14T20:15:08.9300000

A Pegasus3 unit populated with SSDs could take a longer time to format when TRIM is enabled on the Pegasus3 controller.

In order to workaround the issue, disable TRIM on the controller via CLI, and then proceed to format your volume.

To access the promiseutil CLI in macOS, open the Terminal located at /Applications/Utilities/Terminal.app
In the Terminal Window, type promiseutil
```
PromisemacOShost:~ promise$ promiseutil
```
Disable TRIM via promiseutil (CLI):
```
ctrl -a mod -s "trim=disable"
```
The above command is a hidden CLI command, and will return back to the CLI prompt if executed properly:

Example Disabling TRIM:
```
cliib> ctrl -a mod -s "trim=disable"

cliib>
```
Once you have formatted your volume, enable TRIM support again:
```
ctrl -a mod -s "trim=enable"
```
The above command is a hidden CLI command and will return back to the CLI prompt if executed properly.

Example Enabling TRIM:
```
cliib> ctrl -a mod -s "trim=enable"

cliib>
```
Currently, there is no way to determine if TRIM is enabled or not when executing a ctrl -v command in the CLI.

If you attempt to re-enter the same command twice, the CLI will return an error:

cliib> ctrl -a mod -s "trim=disable"
Error (0x8030): there is not any change to the settings
