HP 3PAR Solaris Implementation Guide

WARNING! Failure to claim the HP 3PAR StoreServ Storage as an HP 3PAR array will affect the
way devices are discovered by the multipathing layer.
WARNING! The minimum supported software installation version for VxDMP_5.0MP3 is
VxDMP_5.0MP3_RP1_HF3 with vxdmpadm settune dmp_fast_recovery=off. This tunable
can be left at default values with later versions VxDMP_5.0MP3_RP2_HF1 and
VxDMP_5.0MP3_RP3.
CAUTION: You may need to reboot the host if you wish to reuse VLUN numbers with the following
VxDMP versions: VxDMP_5.0MP3_RP3 or VxDMP_ 5.1. Veritas has an enhanced data protection
code that may be triggered if a VLUN number is reused:
Data Corruption Protection Activated
Using Sun StorageTek Traffic Manager Multipathing (Native Multipathing/MPxIO)
The Solaris 10 and 11 OSs contain the Sun StorageTek Traffic Manner (SSTM), the Solaris FC,
and storage multipathing software. The following notes apply for various OS versions.
Sun StorageTek Traffic Manager (SSTM/MPxIO), the Solaris FC, and storage multipathing software
are installed as part of the Solaris SAN packages for Solaris 8 and 9.
Edit the /kernel/drv/scsi_vhci.conf file for Solaris 8, 9, or 10 to set round-robin,
Active/Active multipathing of HP 3PAR devices.
HP 3PAR OS 2.3.x and HP 3PAR OS 3.1.x
device-type-scsi-options-list =
"3PARdataVV", "symmetric-option",
"3PARdataSES", "symmetric-option";
symmetric-option = 0x1000000;
device-type-scsi-options-list =
"3PARdataVV", "symmetric-option";
symmetric-option = 0x1000000;
NOTE: Do not make the edits shown above in the scsi_vhci.conf file for Solaris 11, which
uses host persona 2 and enables asymmetric logical unit access (ALUA).
Enabling SSTM/MPxIO Multipathing for Solaris 10 and 11
To enable the SSTM for all HBAs on Solaris 10 and 11 systems, issue the stmsboot -e command.
To disable multipathing, issue the stmsboot -d command.
This step, which enables multipathing, requires a host reboot.
CAUTION: When running Solaris 10 MU7, enabling SSTM on a fresh install by using stmsboot
-e can corrupt the fp.conf configuration. To avoid this, disable the fp mpxio by issuing the
following command:
stmsboot -d -D fp
You should then be able to run stmsboot -e successfully without loss of the fp HBA.
For detailed installation instructions, consult the Solaris Fiber Channel and Storage Multipathing
Administration Guide.
