Could any one people tell me what the wrong with this error and how can exatly solve this problem ?

Note: Before this problem occur, there was cut in electric power for two times . But we didn't have any impact, because we have already transferred to second UBS electric. But I'm only worried about that error.

thanks

Have a look on your EMC disk storage or raise a call with EMC
Make sure the disks has recoved

if you document your system you can see what the disk (hdisk57) was used for
lspv should show you what the disk was used for

also try to do the following on your system

cfgmgr
lsvg |lsvg -il
lsvg |lsvg -ip

Look for missing disks , vg , lv etc
