/dev/dsk/c1t14d0 00002 stale (Also hav write errors on STM)

Stale PV shared with 4 Logical volumes...and they all are not mirrored....

--- Distribution of physical volume ---
LV Name LE of LV PE for LV
/dev/vg03/lvsap23 126 126

This case how do we recover the stale...?
If incase we need to replace the disk...what is the procedure...?

Thanks in advance....

Hi,

"Mirror copies 1" means /dev/vg03/lvswap3 *is* mirrored: there is one complete copy on /dev/Dsk/c1t10d0 and another on c1t14d0.

Just mirror the lvswap3 to a new PV, and then use "lvreduce -m" to remove the mirror component that's currently on c1t14d0.

If the other LVs on c1t14d0 are also mirrored, do the same for them too.

If they are not mirrored but still readable, backup their data as soon as possible! Then mirror them to the new PV, and remove the mirror half that's on c1t14d0.

The document linked by rariasn is very useful too.
