HP 3PAR Solaris Implementation Guide

New VLUNs that are exported while the Solaris host is running will not be registered on the host
until the following host command is issued on a Solaris 8, 9 Host:
# devfsadm -i sd
Before they can be used, newly-discovered VLUNs need to be labeled using the Solaris format
or format -e command.
Discovering LUNs for Solaris qlc and emlxs Drivers
In direct-connect mode, new VLUNs that are exported while the Solaris host is running will be
discovered automatically.
In fabric mode, the Solaris driver stack will not make the HP 3PAR StoreServ Storage target port
and its exported devices accessible until they are configured using the Solaris cfgadm command.
For instance, when the HP 3PAR StoreServ Storage and the Solaris host are first connected, and
the host is booted, no devices from the HP 3PAR StoreServ Storage will appear in the Solaris
format command's output. The host server port WWNs will also not show up when using the
HP 3PAR OS CLI showhost command.
To make the ports accessible, issue the Solaris cfgadm -al command to verify the logical
connections of the configuration. This will also scan for new targets. However, new LUNs will not
appear in the Solaris format command's output until the connections are configured using the
Solaris cfgadm -c configure command.
All HBA ports that connect to the HP 3PAR StoreServ Storage in fabric mode, should be configured
using the cfgadm -c command, as follows:
# cfgadm -c configure c8
# cfgadm -c configure c9
# cfgadm -c configure c10
# cfgadm -c configure c11
NOTE: The cfgadm command can also be run on a per target basis:
# cfgadm -c configure c8::22010002ac000040
Once configured, the HP 3PAR StoreServ Storage VLUNs show up in the output from the Solaris
format command as devices and are thus available for use on the host.
The device node designation is comprised of 3 components:
• c -- represents the host HBA port
• t -- represents the target's WWPN
• d -- represents the LUN number
Therefore /dev/rdsk/c8t22010002AC000040d2s2 is a device node for VVC in the following
example that is exported from port 2:0:1 of the HP 3PAR StoreServ Storage, serial number 0x0040
to host port c8, as LUN 2.
