Hello,

to sync all logical volumes in that particular VG, you can also use:

# vgsync /dev/vg_rac &

Hi,

It looks one of the physical volume is missing on which the primary copy of lv is residing.


you need to find the pv key to reduce the stale copy.

#lvdisplay -v -k /dev/vg_rac/ora_ocr

(note down the PV KEY under second column, which was showing PX_NOPV)
then remove the primary copy of the lv using pvkey.

#lvreduce -m 0 -k /dev/vg_rac/ora_ocr

Now lv should have one copy of data without stale. check with lvdisplay.

#lvdisplay -v /dev/vg_rac/ora_ocr

Now you need to fix the disk issue which is missing and remirror it.

Hope it helps

of course, c1t2d0s3 could have failed as well.

check the results of ioscan to see if you've any NO_HDW indications

[OldSchool]

actually i noted the wrong disk. scan the results for the NO_HDW anyway.
