Very well.

I have seen the (R) in the gui often in the past, but I cannot now
verify what conditions caused it to appear.  I am certain that setting
the volumes explicitly to read-only was not done.

Besides manually setting it, the read-only flag will also be set if a
volume is forced to be recycled.

$ mminfo -r 'volume,state,volflags,volretent'
 volume           flags expires
DLT.001                undef
$ nsrmm -o recyclable DLT.001
Mark DLT tape DLT.001 as recyclable? y
$ mminfo -r 'volume,state,volflags,volretent'
 volume           flags expires
DLT.001        E  r    expired

Further, this appears to happen when 'nsrim' marks it so.  I've taken a
tape that is still appendable and marked the only saveset on it
recyclable....

$ nsrmm -o recyclable -S 533865729
Mark save set 533865729 as recyclable? y
$ mminfo -r 'volume,state,%used,volflags,volretent'
 volume             (%) flags expires
DLT.001              6%     undef

Then I ran nsrim...

$ nsrim -X
nsrserver:/, 0 browsable cycle(s)
0 browsable files of 40235 total, 0 KB recoverable of 560 MB total

DLT.001:  564 MB used,     1 save sets, appendable->recyclable, 1
recyclable save sets
$ mminfo -r 'volume,state,%used,volflags,volretent'
 volume             (%) flags expires
DLT.001        E     6% r   expired

It didn't mark the tape 'full', but it did mark it recyclable and
read-only.

I agree.  (and this is the topic that started the thread).

I don't think so.  I've commonly seen the flags in 5.x and 6.x and I've
never (or at least very rarely) set them.  Now I have often forced tapes
recyclable due to scripting outside of the networker retention scheme,
so that may count as being set by a human.

Even so, the 'nsrim' above also set it...
