Note the GUID of the LUN you created in the list of LUNs. For example,
g600144f09c96cca900005190bfc4000a.
Note:
After creating the LUN, ensure that the Write cache enabled check box is
deselected. You can find this check box in the Protocols tab of the LUN.
F.3.1.4 Disable the Write Cache
You must disable the write cache on the LUN permanently by doing the following:
1.
Log in to the compute node for which you identified the initiator node name as
described in Create an iSCSI Initiator .
2.
Edit the
/kernel/drv/sd.conf
file.
3.
Add the following to the
sd.conf
file:
sd-config-list="SUN ZFS Storage 7120","write-cache-disable",
"SUN ZFS Storage 7320","write-cache-disable",
"SUN ZFS Storage 7420","write-cache-disable",
"SUN ZFS Storage 7335","write-cache-disable";
write-cache-disable=1,0x00008,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0;
4.
Restart the compute node by running the
reboot
command.
F.3.1.5 Format the LUN
Before the compute node can use the LUN, you must format the LUN. You can format
the LUN by doing the following:
1.
Log in to a compute node as the
root
user.
2.
Run the
iscsiadm
commands to discover the iSCSI targets from the compute
node:
# iscsiadm add discovery-address IPoIB_address_of_the_storage_appliance
# iscsiadm modify discovery -t enable
In this example,
IPoIB_address_of_the_storage_appliance
is the IP
address of the storage appliance on the IPoIB network.
3.
Run the following command to load drivers, attach device instances, create logical
links to device nodes, and load the device policy for iSCSI:
# devfsadm -c iscsi
4.
Identify the disk you should format and label by running
echo | format
as
follows:
# echo | format
