Solaris SVM error when attaching a new disk – metattach I/O Error

I was trying to increase a metadevice with another disk but I was getting an I/O error

root@solaris:~ # metattach d200 /dev/rdsk/emcpower46c
metattach: solaris: /dev/dsk/emcpower46c: I/O error

Nothing strange was appearing in the emcpower disk

root@solaris:~ # powermt display dev=emcpower46
Pseudo name=emcpower46a
Symmetrix ID=000287752010
Logical device ID=01A1
state=alive; policy=SymmOpt; priority=0; queued-IOs=0

A friend here at work asked if the disk has a label. It didn’t have one.

selecting emcpower46e
[disk formatted]
Disk not labeled. Label it now? yes

After that I was able to increase the metadevice.

root@solaris:~ # metattach d200 /dev/rdsk/emcpower46c
d200: component is attached
