attached vs unattached pv

Dear all,

am confused about these errors and i need to know which means that the pv is attached or unattached

this one means what, attached or unatteched pv ?
# vgchange -a y /dev/vg01
vgchange: Warning: Couldn't attach to the volume group physical volume "/dev/dsk/c0t3d0": A component of the path of the physical volume does not exist. Volume group "/dev/vg01" has been successfully changed.

this one means what, attached or unatteched pv ?

# vgchange -a y /dev/vg01
WARNING
VGCHANGE: WARNING: COULDN'T ATTACH TO THE VOLUME GROUP PHYSICAL VOLUME "/dev/dsk/cXtXd0"

THE PATH OF THE PHYSICAL VOLUME REFERS TO A DEVICE THAT DOES NOT EXIST, OR IS NOT CONFIGURED INTO THE KERNEL.

regards

Re: attached vs unattached pv

The device dev/dsk/c0t3d0 belongs to this VG, but the system cannot access it. Is it visible in ioscan? Maybe a dead drive?

Hope this helps!

Re: attached vs unattached pv

Try pvdisplay /dev/dsk/c0t3d0

Esle you can try diskinfo on the disk to verify the disk.

Analyzing the error it seems that the VG is activated ..but the particular PV is unavailable..

Pls check the PV availability and reply..

Hello Joeysf,

As already said you need to check the disk:
# ioscan -fnC disk <<=== CLAIMED??
# diskinfo /dev/rdsk/c0t3d0 <<== Size??

As the VG is activated, you can also check:
# vgdisplay -v vg01
Cur PV <<==
Act PV <<==

Regds..
