VMware vSphere SAN Space Issues

We are running out of space and what is the best way to create space for one of our VMs.
Is it safe to migrate live  one of the LUN (for One HD) without corrupting the data.
Could I consider deleting some of the files.  Please see attachment. Thanks.

Perfectly safe to migrate live from one LUN to another LUN, if you have a license for Storage vMotion.

We have SDRS (Storage DRS) and it Live Migrates or Storage vMotions automatically every day....with no issues with Live VMs.

So you have options...

1, Migrate to larger LUN.

2. Increase the space of the LUN.

both can be done live, and do not affecting running VMs.

Thanks for the advice. However, In the attachment I had sent  earlier, could I consider deleting some of the files like .hlog,  and plenty of  ctk.vmdk etc.  Not too sure what is the difference between .hlog and .log?

There was no attachment, those files are insignificant.

Unless you have a snapshot.
