Installing and configuring the FCAs

Install and configure the FCA driver software and setup utilities according to the manufacturer's

instructions. Configuration settings specific to the XP array differ depending on the manufacturer.

Specific configuration information is detailed below.

The FCA configuration process may require you to enter the WWN for the array port(s) to which the

FCA connects. Your HP representative can provide you this information or you may display this

information on the SAN switch.

The queue depth parameter (max_throttle) for the devices must be set according to one of the options

specified in

Table

Table 3 Max throttle (queue depth) requirements for the devices

Queue depth op-

tion

Option 1

Option 2 (preferred)

NOTE:

You can adjust the queue depth for the devices later as needed (within the specified range) to optimize

the I/O performance.

The required I/O time-out value (TOV) for devices is 60 seconds (default TOV=60). If the I/O TOV

has been changed from the default, change it back to 60 seconds by editing the sd_io_time or

ssd_io_time parameter in the /etc/system file.

You may also need to set several other parameters (such as FC fibre support). See the user

documentation that came with your FCA to determine whether other options are necessary to meet

your operational requirements.

Installing and configuring Sun Solaris for the XP disk array

Requirements

XP10000, XP12000, SVS 200: Queue_depth

XP20000, XP24000: Queue_depth

CAUTION:

The number of issued commands must be completely controlled. Because queuing

capacity of the disk array is either 1024 or 2048 per port (depending on the disk

array), you must adjust the number of issued commands from Solaris system to

less than 1024 or 2048. Otherwise, memory allocate failed messages may occur

on the Solaris system, and all read/write I/O may stop, causing the system to

hang.
