I'm having a strange issue.
I'm running Veritas 9.1 Rev 4691
I have a Dell PowerVault 136T tape library with 4 SDLT tape drives.
I've confirmed with Dell support that all drivers and firmware are up-to-date and that there are no problems with the tape library itself.
I have a media set that has been configured to "Infinite - Don't Allow Overwrite" and "Infinite - Allow Append". There are currently 10 tapes already assigned to that media set. 7 of which are full and have a capacity of 0. And as expected, these tapes have "Not Appendable" under the Appendable Until column.
The other 3 tapes have some data written on them. However, they do still have space remaining. (see attached picutre). But, as you can see, those tapes are also reading as "Not Appendable" under the Appendable Until column. Why is that? Why is a tape that has space on it, and part of an Infinite Appendable media set NOT appendable?

I've tried cleaning all the tape drives. I've tried moving the offending tapes to another media set and then moving them back in hopes it'll reset the appendable period. The tapes are brand new. Have no Hard Read or Write errors.
Any ideas?
