    asmlib, device paths not showing?




      Iv just created a test system running  RAC on Linux:

      uname -a

      Linux collabn1.vm.ardentperf.com 2.6.18-238.el5 #1 SMP Tue Jan 4 15:24:05 EST 2011 i686 i686 i386 GNU/Linux


      Iv never actually worked with Oracle on Linux and am a bit confused with the following:


      I want to check the paths of the disks I have configured in the +DATA diskgroup im using:


      SQL> select group_number, name from v$asm_diskgroup;

      ------------ ----------
                 1 BACKUP
                 2 DATA
                 3 FRA


      SQL> col path for a30
      SQL> col name for a10
      SQL> /

      GROUP_NUMBER NAME            LABEL                           PATH                             TOTAL_MB
      ------------ ---------- ------------------------------- ------------------------------ ----------
                 1                     BACKUP     BACKUP                       ORCL:BACKUP                       8189
                 2                     DATA          DATA                            ORCL:DATA                            8189
                 2                     DATA2        DATA2                          ORCL:DATA2                          8189
                 3                     DATA3        DATA3                          ORCL:DATA3                          16378


      collabn1:/home/oracle[+ASM1]$ asmcmd

      ASMCMD> lsdsk -G DATA




      ASMCMD> exit

      collabn1:/home/oracle[+ASM1]$ /etc/init.d/oracleasm querydisk -p DATA

      Disk "DATA" is a valid ASM disk

      /dev/sdb1: LABEL="DATA" TYPE="oracleasm"

      collabn1:/home/oracle[+ASM1]$ /etc/init.d/oracleasm querydisk -p DATA2

      Disk "DATA2" is a valid ASM disk


      For the second disk DATA2 no information is shown for the device path.....?


      Any ideas why not?


      Any help would be appreciated
