For information about the types of Oracle Database files that you can store by using hardware RAID support, see Storage Management Requirements.
See the Oracle Solaris Cluster hardware documentation for information about how to create LUNs.
The following example lists output from the format command.
# format 0. c0t2d0 <SUN18G cyl 7506 alt 2 hd 19 sec 248> /sbus@3,0/SUNW,fas@3,8800000/sd@2,0 1. c0t3d0 <SUN18G cyl 7506 alt 2 hd 19 sec 248> /sbus@3,0/SUNW,fas@3,8800000/sd@3,0 2. c1t5d0 <Symbios-StorEDGEA3000-0301 cyl 21541 alt 2 hd 64 sec 64> /pseudo/rdnexus@1/rdriver@5,0 3. c1t5d1 <Symbios-StorEDGEA3000-0301 cyl 21541 alt 2 hd 64 sec 64> /pseudo/rdnexus@1/rdriver@5,1 4. c2t5d0 <Symbios-StorEDGEA3000-0301 cyl 21541 alt 2 hd 64 sec 64> /pseudo/rdnexus@2/rdriver@5,0 5. c2t5d1 <Symbios-StorEDGEA3000-0301 cyl 21541 alt 2 hd 64 sec 64> /pseudo/rdnexus@2/rdriver@5,1 6. c3t4d2 <Symbios-StorEDGEA3000-0301 cyl 21541 alt 2 hd 64 sec 64> /pseudo/rdnexus@3/rdriver@4,2
Use the cldevice (1CL) command for this purpose.
The following example lists output from the cldevice list –v command.
# cldevice list -v DID Device Full Device Path ---------- ---------------- d1 phys-schost-1:/dev/rdsk/c0t2d0 d2 phys-schost-1:/dev/rdsk/c0t3d0 d3 phys-schost-2:/dev/rdsk/c4t4d0 d3 phys-schost-1:/dev/rdsk/c1t5d0 d4 phys-schost-2:/dev/rdsk/c3t5d0 d4 phys-schost-1:/dev/rdsk/c2t5d0 d5 phys-schost-2:/dev/rdsk/c4t4d1 d5 phys-schost-1:/dev/rdsk/c1t5d1 d6 phys-schost-2:/dev/rdsk/c3t5d1 d6 phys-schost-1:/dev/rdsk/c2t5d1 d7 phys-schost-2:/dev/rdsk/c0t2d0 d8 phys-schost-2:/dev/rdsk/c0t3d0
In this example, the cldevice output identifies that the raw DID that corresponds to the disk arrays' shared LUNs is d4.
The following example shows the output from the cldevice show for the DID device that was identified in the example in Step 3. The command is run from node phys-schost-1.
# cldevice show d4 === DID Device Instances === DID Device Name: /dev/did/rdsk/d4 Full Device Path: phys-schost-1:/dev/rdsk/c2t5d0 Replication: none default_fencing: global
For information about configuring DID devices into a zone cluster, see How to Add a Global Storage Device to a Zone Cluster (clsetup) in Oracle Solaris Cluster Software Installation Guide or How to Add a DID Device to a Zone Cluster (CLI) in Oracle Solaris Cluster Software Installation Guide .
Use the format (1M) command, fmthard (1M) command, or prtvtoc (1M) for this purpose. Specify the full device path from the cluster node where you are running the command to create or modify the slice.
For example, if you choose to use slice s0, you might choose to allocate 100 GB of disk space in slice s0.
To specify the raw device, append sN to the DID device name that you obtained in Step 4, where N is the slice number.
For example, the cldevice output in Step 4 identifies that the raw DID that corresponds to the disk is /dev/did/rdsk/d4. If you choose to use slice s0 on these devices, specify the raw device /dev/did/rdsk/d4s0.
Next Steps
Ensure that all other storage management schemes that you are using for Oracle Database files are installed. After all storage management schemes that you are using for Oracle Database files are installed, go to Chapter 3, Registering and Configuring the Resource Groups.
