I have two node RAC database which use two EMC storages(RAID5), I have two luns in each diskgroup with normal redundancy and configured multipathing for luns.
Recently one of the luns in diskgroup +EXAMPLE1 crashed and all CRS stopped. Then i comented crashed lun in multipath.conf file and started cluster and database successfully .
But then i saw that all discs(luns) on second storage where one of the luns crashed are dropped from asm diskgroups.
Can anybody explain me what this problem caused
