Enabling MPxIO

To enable MPxIO for HP storage devices, the appropriate information for device-type-scsi-options-listneed to be added in the /kernel/drv/scsi_vhci.conf file.

1.Use a text editor to change the configuration file. For example:

# vi /kernel/drv/scsi_vhci.conf

2.For Solaris 8 and 9 perform the following steps:

a.Change the mpxio-disable parameter to the following: mpxio-disable="no";

b.Verify that the load-balance and auto-failback parameters are set to the following values (the default setting may vary depending on the patch level / OS version):

load-balance="none"; auto-failback="disable";

c.Add the following lines to cover all HP arrays:

device-type-scsi-options-list =

"HP

HSV101",

"symmetric-option",

"COMPAQ

HSV111",

"symmetric-option",

"HP

HSV2",

"symmetric-option",

"HP

OPEN",

"symmetric-option";

symmetric-option = 0x1000000;

NOTE:

Enter six spaces after ”HP” and two spaces after “COMPAQ”.

3.For Solaris 10 (patch 118833-24 for SPARC, patch 118855-19 for x86), the scsi_vhci driver is capable of detecting Asymmetric Logical Unit Access (ALUA) compliant devices advertised in the Target Port Group Support (TPGS) field. The EVA 4000/6000/8000 and the EVA 3000/5000

V4 are ALUA compliant arrays. Add the following lines to cover all HP arrays:

device-type-scsi-options-list

=

"HP

OPEN", "symmetric-option";

symmetric-option = 0x1000000;

 

NOTE:

Enter six spaces after ”HP”.

4.Depending on the Solaris version, select one of the following options:

a.For Solaris 8 or 9—run a reconfiguration reboot in order to activate the changes:

#reboot -- -r

b.For Solaris 10 (SPARC)—run the stmsboot command and confirm the reboot:

#stmsboot –e

c.For Solaris 10 (x86)–reboot the system to load the new definition if you are configuring for XP. Configuring for EVA does not require a reboot since definition has already been configured.
