HP StorageWorks 1000 Modular Smart Array installation guide
81
IMPORTANT:
In multipath configurations:
•
Verify that both HBAs in each server have been granted access to the storage.
•
In active/active configurations, manually assign a preferred path (controller ownership) for each
LUN. By default, MSA firmware initially assigns ownership of all LUNs to the controller in slot
one (front-right) of the MSA. Then, based on access patterns and I/O load, the firmware
automatically re-assigns ownership of the LUN between the controllers to balance the load. If
your environment controls load balancing from the host, you must manually assign the preferred
path for each LUN.
•
Starting with version 8.3, OpenVMS contains path optimization software that automatically
reassigns storage connections to their optimized path.
Perform these tasks using your chosen configuration utility. Refer to the appropriate user
documentation for procedural instructions.
Go to
Table 13
: ”
Hard drive information
” on page 112 and
Table 14
: ”
Array (LUN) information
” on
page 116 to record information about your storage.
Assigning ID Numbers to the controllers and LUNs
When configuring your MSA, you must assign a unique ID number to each MSA controller
and
to
each MSA storage LUN.
See the MSA 1000/1500 Command Line Interface user guide for specific instructions.
