Systems

Figure 7. Create a new storage group in Dell|EMC storage manager
5. Reboot target servers to discover the Dell|EMC disks.
6. Configure DM Multipath for the Dell|EMC disks.
7. Change ownership of the Dell|EMC disks to oracle:dba. For example,
brw-rw---- 1 oracle dba 253, 67 Jul 5 17:05 /dev/mapper/data1p1
brw-rw---- 1 oracle dba 253, 58 Jul 5 17:05 /dev/mapper/data2p1
brw-rw---- 1 oracle dba 253, 64 Jul 5 17:05 /dev/mapper/data3p1
brw-rw---- 1 oracle dba 253, 57 Jul 5 17:05 /dev/mapper/data4p1
brw-rw---- 1 oracle dba 253, 63 Jul 5 17:05 /dev/mapper/data5p1
brw-rw---- 1 oracle dba 253, 56 Jul 5 17:05 /dev/mapper/data6p1
brw-rw---- 1 oracle dba 253, 62 Jul 5 16:31 /dev/mapper/fra1p1
brw-rw---- 1 oracle dba 253, 61 Jul 5 16:31 /dev/mapper/fra2p1
brw-rw---- 1 oracle dba 253, 55 Jul 5 16:21 /dev/mapper/fra3p1
brw-rw---- 1 oracle dba 253, 60 Jul 5 15:44 /dev/mapper/fra4p1
brw-rw---- 1 oracle dba 253, 59 Jul 5 16:21 /dev/mapper/fra5p1
brw-rw---- 1 oracle dba 253, 49 Jul 5 16:21 /dev/mapper/fra6p1
8. The ASM disks from the source database can now be seen from the service oracleasm
listdisks command output. In the following example, ASM disks data[1-6] and fra[1-6] are from
the source Dell|EMC storage system; ASM disks data[7-12] and fra[7-12] are from the target Dell
Compellent storage system.
