DataDirect Networks SFA™ OS 1.5.3.0 Release Notes Revision B | 15
6.0 Recommended Practices
The recommended best practices for the SFA12K-40, SFA12K-20, SFA12K-20E, SFA10K-X,
SFA10K-M, and S2A6620 with SFA OS version 1.5.3.0 include:
• SS6000 DEM and I/O module replacement.
For SS6000 DEM and I/O module replacement, see the SFA OS User Guide for
the procedures.
• Reduce host I/O load during background initializations.
When a storage pool is in the process of being initialized, a significant internal I/O
load is generated. To avoid poor performance, DDN recommends that heavy host
I/O loads be avoided until pool initialization has completed.
• On hosts that are directly connected, if the configuration is cleared, the
Fibre Channel initiators may not log back into the subsystem.
This results in no initiators being available to assign to new presentations. To
correct this, do a rescan from the host before setting up your presentations.
This does not apply to the SFA12K-40, SFA12K-20, and SFA12K-20E.
• Disk firmware upgrades.
Before performing a disk firmware upgrade, scp the .DDN file to both controllers.
This avoids a situation where a controller attempts to perform the upgrade but
can’t find the .DDN file.
• Firmware upgrades should be done during low usage periods whenever
possible.
As upgrading your system will interrupt I/O operations as paths fail over, be
aware of the possibility of increased I/O latencies during the upgrade operation.
Prior to upgrading your firmware, DDN recommends your reviewing the system
logs to ensure the system is running cleanly. DDN also recommends your
allowing any rebuilds and forced verify jobs to complete and pausing any running
verify jobs.
