HP 3PAR Solaris Implementation Guide

HP 3PAR StoreServ Storage volume serial number (VV_WWN). LUN number 50 was used for the
first time to present a device.

On removing demo.50 volume and exporting checkvol at the same LUN number 50, the host
shows the new volume with the serial number of the earlier volume, demo.50
(50002AC01188003E) and not the new volume serial number (50002AC011A8003E).

CAUTION: Issue devfsadm -C to clear any dangling /dev links and reboot the host to correct
the device serial number or to reuse the LUN number.
• Solaris 10 or 11 can support the largest VV that can be created on an HP 3PAR StoreServ
Storage system at 16 terabytes. VVs of 1 terabyte and larger are only supported using the
Solaris EFI disk label and appear in the output of the Solaris format command without
cylinder/head geometry.
• All I/O to an HP 3PAR StoreServ Storage port should be halted before running the HP 3PAR
OS CLI controlport command on that port. The HP 3PAR OS CLI controlport command
executes a reset on the storage server port while it runs. The reset is done on a per-card basis,
so any port reset (0:3:1) will cause reset on the partner port (0:3:2) and causes the port to
log out and back to a ready state. This event will be seen on the host as a transient device
missing event for each HP 3PAR StoreServ Storage LUN that has been exported on that port.
In addition, if any of the exported volumes are critical to the host server OS (e.g., the host
server is booted from that volume), the host server should be shut down before issuing the
HP 3PAR OS CLI controlport command.
Discovering LUNs on Fibre Channel Connections
This section provides tips for discovering LUNs depending on the type of HBA driver and connection
configuration that is being utilized by the Solaris host. For examples of discovering LUNs for various
configurations, seeChapter 8 (page 50).

NOTE: The HP 3PAR StoreServ Storage targets appear with their World Wide Port Names
associated with the C number of the host HBA port they are logically connected to, but are initially
in an unconfigured state.
