ioscan shows CLAIMED but do not appear in vgdisplay

Hi gurus,

We have 4 disks under vg00 but disk c4t8d0 is not appear when we execute vgdisplay command. From the ioscan, it shows CLAIMED. Diskinfo command shows size 0 KBytes. It's alternate boot disk. We plan to change the disk. Do u mind to share with us steps that we need to take to replace the disk?

 

ioscan -fn
