HP XP P9000 Configuration Guide (AV400-96525, November 2012)

3. To set the queue depth, add the following to the /etc/system file:
set sd:sd_max_throttle = x
set ssd:ssd_max_throttle = x for Oracle generic FCA
(for x value, see Table 20 (page 60))
Example:
set sd:sd_max_throttle = 16 <— Add this line to /etc/system
set ssd:ssd_max_throttle = 16 <— Add this line to /etc/system (for Oracle generic FCA)
Configuring FCAs with the Oracle SAN driver stack
Oracle branded FCAs are only supported with the Oracle SAN driver stack. The Oracle SAN
driver stack also supports current Emulex and QLogic FCAs.
NOTE: Ensure host group mode 7 is set for the P9000 array ports where the host is connected
to enable automatic LUN recognition using this driver.
To configure the FCA:
• Check with your HP representative to determine which non-Oracle branded FCAs are supported
by HP with the Oracle SAN driver Stack, and if a specific System Mode or Host Group Mode
setting is required for Oracle and non-Oracle branded FCAs.
• For Solaris 8/9, install the latest Oracle StorEdge SAN software available from http://
www.oracle.com with associated patches. Use the Oracle supplied install_it script that is
provided with the software to automate installation.
• For Solaris 10, use the Oracle update manager to install the latest patches.
• To use Oracle StorEdge Traffic Manager (MPxIO)/Oracle Storage Multipathing, edit the driver
configuration file /kernel/drv/scsi_vhci.conf to add the Vendor ID and Product ID
to the “device-type-scsi-options-list” parameter. See the Oracle StorEdge Traffic Manager
Software Installation and Configuration Guide or Solaris Fibre Channel and Storage
Multipathing Administration Guide, and HP StorageWorks MPxIO for Oracle Solaris
Application Notes, for further details.
• For Solaris 8/9 change to “no” as shown:
mpxio-disable="no";
• For all Solaris releases, add the following lines:
device-type-scsi-options-list =
"HP OPEN", "symmetric-option";
symmetric-option = 0x1000000;
NOTE: There must be exactly 6 spaces between HP and OPEN.
• Instead of using the default round-robin algorithm, add the following lines in addition to the
previous lines for systems with a large amount of sequential I/O activity:
device-type-mpxio-options-list=
"device-type=HP OPEN", "load-balance-options=logical-block-options";
logical-block-options="load-balance=logical-block", "region-size=18";
NOTE: There must be exactly 6 spaces between HP and OPEN.
