Installing And Configuring The Disk Array; Microprocessor Port Sharing - HP StorageWorks XP10000 - Disk Array Configuration Manual

Installing and configuring the disk array

The HP service representative performs these tasks:
• Assembling hardware and installing software
• Loading the microcode updates
• Installing and formatting devices
• Configuring array groups and creating LDEVs
After these tasks are finished, use XP Remote Web Console, XP Command View, or XP Array Manager
to complete the remaining tasks listed below. For procedures, refer to the applicable user guide
available at:
http://www.hp.com/support/manuals.
If you do not have these programs, your HP service representative can perform these tasks for you.
IMPORTANT:
For optimal performance when configuring any XP disk array with a Tru64 host, HP does not
recommend:
• Sharing of CHA (channel adapter) microprocessors
• Multiple host groups sharing the same CHA port
NOTE:
As illustrated in the following table, there is no microprocessor sharing with 8–port module pairs.
With 16– and 32–port module pairs, alternating ports are shared.
