FAQ

This page addresses typical questions on SCSI2Pi and SCSI Control.

SCSI2Pi/PiSCSI
What are the main advantages of SCSI2Pi compared to PiSCSI?
SCSI2Pi offers additional functionality (e.g. SASI support), higher transfer rates, improved compatibility, improved tools and bug fixes. For SCSI2Pi there are installation packages with the binaries, which means that no time-consuming compilation is required.
Is there a web interface for SCSI2Pi?
Yes, because SCSI2Pi is compatible with the PiSCSI web interface. By installing/de-installing SCSI2Pi you can easily switch between PiSCSI and SCSI2Pi.
Installation
Why does installing SCSI2Pi only need a few seconds?
For SCSI2PI installation packages with the binaries are provided. These are installed in a matter of seconds.
SCSI Control app
Is SCSI Control also compatible with PiSCSI, or only with SCSI2Pi?
Yes, SCSI Control can also be used with PiSCSI. An upgrade to SCSI2Pi is recommended, though, in order to profit from the full functionality.
Can SCSI Control manage several boards/setups?
Yes, several board and setups, resp., can be managed. The active board/setup is selected from list of available configurations.
Device overview
Where can I edit the device groups saved in the device overview?
Like all other groups the groups saved in the overview can be edited in the device groups view. Loading an saving device groups in the device overview is offered mainly for convenience. The device groups view provides more means for editing device groups.
Device types
Can SCSI Control hide device types I am not interested in, e.g. SASI drives?
Yes, you can select the device types taken into account by SCSI Control in the app settings.
Device profiles
When creating a drive based on a device profile, does the image file size have to match the drive capacity?
No, this is not required. Only when a capacity is entered in the edit field SCSI Control expects the size of the image file to be identical with this capacity. After choosing a device profile the data in the edit fields can be modified before creating a device. The device profile is just a template.
Can my own device profiles have the same names as the standard profiles?
Yes, this is possible. In this case your own profile replaces the standard profile of the same name.
Device groups
How can I make good use of device groups?
A typical use case is a scenario with several computers. In most cases for each computer you need a different set of peripherals. Just create a device group for each set.
Image files
Why are some image files missing in the list of available files?
Files may be missing because a capacitiy was specified for a device but the file size does not match this capacity. (Entering data in the capacity field is optional.) A file is also not displayed when it is already attached to a device.
When does creating/copying/renaming images files > 2 GiB fail?
These operations fail with SCSI Control and the scsictl tool in case Buster is installed on the Pi. It is recommended to update to Bullseye. As soon as Bookworm (successor of Bullseye) becomes available (in the course of 2023) SCSI2Pi will not support Buster anymore anyway.
Push messages
Why don't I receive any push messages with news on the SCSI2Pi project?
Ensure that you have not only permitted SCSI2Pi Control to receive messages within SCSI2Pi Control, but also in the Android notification settings. With Android 13 there were some changes regarding notification permissions.
When does SCSI Control retrieve the SCSI2Pi statistics in order to check for errors?
SCSI2Pi Control only retrieves the statistics if push messages for errors have been enabled, and does so only in an unmetered WiFi. Depending on the Android OS the statistics are retrieved about every 15 minutes.
