To enable MPxIO for storage devices, the appropriate information for device-type-scsioptions-list need 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 =NOTE:
"HP OPEN", "symmetric-option";
symmetric-option = 0x1000000;
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.
