            open asmca, and tell us what are you seeing.

              Also, what do you see from within ASMCMD ?

                Set DISPLAY environment variable, then re-run.
                [oracle@medi02 bin]$ ./asmcmd
                ./asmcmd: line 123: /home/app/11.2.0/grid/bin/perl/bin/perl: No such file or directory

                  you have to export ORACLE_HOME and ORACLE_SID first

                  or
                  [oracle@fran~]$ oraenv
                  ORACLE_SID = [Fran] ? +ASM1
                  The Oracle base has been changed from /u01/app/oracle to /u01/app/grid

                          you did
                          fdisk /dev/sdb
                          and lost 1 disk ..... why did you do it again????

                          Follow this steps, ONLY in the lost disks:

                          1) fidsk /dev/sdX with options "n", "p", "1", "w" <-- in those 3 lost partitions

                          2) /etc/init.d/oracleasm createdisk DSK1 /dev/sdX1 <-- in those 3 lost partitions

                          3) /etc/init.d/oracleasm scandisks
                          4) /etc/init.d/oracleasm listdisks

                          5) export ORACLE_SID= ASM (could it be different ASM1 or +ASM2, check it with "ps -ef | grep asm" and write the same value)
                          6) export ORACLE_HOME= <grid_home>
                          7) execute asmca and recreate groupdisks.
