9 | EXPANDING ORACLE’S VIRTUAL COMPUTE APPLIANCE USING ORACLE ZFS STORAGE APPLIANCE

NFS

Oracle VM requires either the NFS or iSCSI for protocol connectivity. Only one protocol should be chosen. The

following steps outline the NFS configuration on the Oracle ZFS Storage Appliance. Refer to the next section if

iSCSI is more desirable.

1. Create a project called “VCA”:

ZFS:> shares project VCA

2. Set the default user and group to root:

VCA> set default_group=root

VCA> set default_user=root

3. Ensure root access is available to all the Virtual Compute Appliance subnets:

VCA> set

sharenfs="sec=sys,rw=@192.168.4.0/24:@192.168.40.0/24,root=@192.168.4.

0/24:@192.168.40.0/24"

VCA> commit

4. Create a sample share to be imported to Oracle VM:

ZFS:> shares select VCA

VCA> filesystem testshare

VCA> commit

5. Create any additional NFS shares needed to expand Oracle VM’s storage capacity.

6. Repeat this procedure for the second controller if an active/active cluster configuration is being used.

iSCSI

Each compute node on the Virtual Compute Appliance has an IQN identifier that must be manually added to the

Oracle ZFS Storage Appliance.

1. Extract the IQN from a root shell on a Virtual Compute Appliance compute node:

# cat /etc/iscsi/initiatorname.iscsi

InitiatorName=iqn.1988-12.com.oracle:974da248268c

2. Add the IQN to Oracle ZFS Storage Appliance Controller 1:

ZFS:> configuration san iscsi initiators

initiators> create

initiator-000> set alias=vca_computenode_hostname

initiator-000> set initiator=iqn.1988-12.com.oracle:974da248268c

Note: Use the IQN value discovered on the compute node. This is just an example IQN.

initiator-000> commit

3. Repeat the steps above for every compute node.

4. Create an initiator group and add all the IQNs:

initiators> groups

groups> create

group-000> set name=VCA

group-000> set initiators=iqn.1,iqn.2,iqn.3,iqn.4

Note: Use the Tab key to add each IQN value added in Step 3 and Step 4.

group-000> commit
