I have a 1 TB disk I formatted under Linux. I wanted to change the disklabel from:

[...]

sd1> m i
offset: [64]
size: [1953525040]
FS type: [unknown] ext2fs
sd1*> p
OpenBSD area: 64-1953525104; size: 1953525040; free: 0
#                size           offset  fstype [fsize bsize   cpg]
  c:       1953525167                0  unused

sd1*> w
disklabel: DIOCWDINFO: Input/output error
disklabel: unable to write label
sd1*> x

You should consider the 'i' slice in disklabel informational.  It is not a real slice defined/stored in the disklabel, rather it is a 'view' shown with the disklabel of something defined elsewhere, in this case the disk partition table.  To modify it you should use a tool like fdisk(8).  It is shown with the disklabel so you'll know it's occupied so you won't try to use it for OpenBSD purposes.
