HP 3PAR Solaris Implementation Guide

Discovering LUNs for Veritas Volume Manager’s DMP (VxDMP)
If you are using the Veritas Volume Manager's DMP driver, make the newly registered and labeled
VLUNs visible to the DMP layer by issuing the following command:
# vxdctl enable
After issuing this command, the volume can be admitted to and used by Veritas Volume Manager.
Discovering LUNs on iSCSI Connections
To discover new LUNs, issue the Solaris devfsadm -i iscsi command on the host.
You can export new LUNs while the host is serving I/O on existing iSCSI LUNs. If a LUN is exported
to multiple paths on the host, and Solaris multipath I/O is enabled, only one device will be presented
in the format output. The output will be in the form of cXt<VV_WWN>dX, where VV_WWN is the
HP 3PAR StoreServ Storage volume ID.
Do not use both static and dynamic device discovery for a given target as it causes problems
communicating with the iSCSI target device.
Use devfsadm -vC to clear the /dev links of non-existing devices.
You can reduce the amount of time the format command takes to display a device or to label a
disk by enabling the no-check variable NOINUSE_CHECK=1. Enabling the no-checking option is
useful if you have a large number of devices being exported.
All iSCSI error messages will be logged in /var/adm/messages.
The iscsiadm list target command lists all the connected target ports, target devices and LUN
numbers that are exported.
