Lost cause disk?

Hi,

This is probably a lost cause disk issue but I may be lucky and someone in this forum might tell me otherwise

RX7620 has two internal disks on vg00. Root disk is fine, the disk with /opt is not fine

ioscan reports all ok c0t6d0 c3t6d0 both CLAIMED, c3t6 has the problem though as reported by lvm

LVM : Failure in attaching PV (64000/0xfa00/0x2) to the root volume group.

reconnect -r says not ok

diskinfo /dev/dsk/c3t6d0 shows device busy ( presumably as it's part of the VG and lvm is retrying)

At the EFI level I think I am only seeing one disk

I've tried reseating but getting to the end of things to try. In case it's just the disk label that's missing is there a way to get this back?

Thanks

Looks like a dead disk. If the disks are mirrored, you should boot up and replace the disk.
