Hi:

Posible EMC disk is bad?

Use "sympd" to show detailed information about a Symmetrix device:

# sympd show /dev/rdsk/cxtydz

rgs,

It's a silly one but you could also try with a:

pvchange -a y /dev/disk/diskXXX

just in case someone did a pvchange -a N to the disk

Hi Bharat,

check through------>

#pvdisplay -l /dev/dsk/c24t4d1
/dev/dsk/c24t4d1 :LVM_Disk=yes show like that

#lvdisplay -v /dev/vg_omnivdev_04_omnivdev_bkup/lv_tempdir |more

check stale PEs

#bdf /dev/vg_omnivdev_04_omnivdev_bkup/lv_tempdir

and you can also try

#pvchange -a y /dev/dsk/c24t4d1

Deeos
