I have an old Dell SVC2020 SAN that I use for non-critical data from a hardware testing device. Recently, I forgot to turn off the data collector, and now the disk is full. Instead of just halting operations like most disks, my SAN has entered 'emergency mode' and the volume is disconnected from the server.
I'm wondering why this happened. Ideally, I'd like to just delete some data if I could see the volume. Without Dell's support, how can I fix this? There's nothing in the recycle bin and snapshots are disabled. While I could delete the volume, I'd prefer to avoid it if possible, as I need to set some things up afterward. Plus, it would be a good learning experience to resolve this the right way.

Your SAN likely went into emergency mode to protect the data on it once the storage was filled. It’s designed to prevent data loss when the underlying hardware is full. You can try to add additional storage, perhaps by finding disk shelves, or alternatively, free up space by deleting smaller volumes. I would recommend aiming to keep your usage under around 90% to allow for RAID overhead and prevent this issue in the future.
If you’re on SCOS 7.4 and the space you see available is reserved, you won’t be able to use it without support intervention. There’s a chance the system took an emergency snapshot before entering conservation mode which might allow some recovery of space. Otherwise, deleting the volume or adding more capacity seems to be the only path.
The volume may have automatically switched to read-only mode due to reaching capacity. You’ll likely need to delete the volume from the SAN to regain access. Unfortunately, without support, this might be your only option.
