Example--Replacing a Hot Spare in One Hot Spare Pool

# metastat hsp003
hsp003: 1 hot spare
        c0t2d0s2                Broken       5600 blocks
# metahs -r hsp003 c0t2d0s2 c3t1d0s2
hsp003: Hotspare c0t2d0s2 is replaced with c3t1d0s2

In this example, the metastat command makes sure that the hot spare is not in use. The metahs -r command replaces hot spare /dev/dsk/c0t2d0s2 with /dev/dsk/c3t1d0s2 in the hot spare pool hsp003.

Example--Replacing a Hot Spare in All Associated Hot Spare Pools

# metahs -r all c1t0d0s2 c3t1d0s2
hsp001: Hotspare c1t0d0s2 is replaced with c3t1d0s2
hsp002: Hotspare c1t0d0s2 is replaced with c3t1d0s2
hsp003: Hotspare c1t0d0s2 is replaced with c3t1d0s2

In this example, the keyword all replaces hot spare /dev/dsk/c1t0d0s2 with /dev/dsk/c3t1d0s2 in all its associated hot spare pools.
