ACS Feature Support

The following sections provide details for specific ACS features.

Maximum Host Connections

The maximum number of host connections is 96 for the table of known connections. A

connection is unique to the node WWN, port WWN, and controller port. This table is

maintained in the NVRAM of the controller. If the table contains 96 entries, new

connections cannot be added unless unused entries are deleted. Otherwise, a host

attempting FC login is rejected from becoming a connection into the connection table,

but not necessarily from the fabric.

Rolling Upgrades

The ACS upgrade path has been reworked to provide a more friendly and seamless

operation. However, the documented process must be followed carefully to ensure a

smooth transition. For more information on upgrade and downgrade procedures, refer

to the HSG80 Array Controller ACS Version 8.7 Maintenance and Service Guide.

ACS Version 8.7 supports both the dual-redundant controller rolling upgrade and

dual-redundant controller shutdown upgrade methods. The rolling upgrade method

allows the host system to continue I/O activity, with minimal impact, while each

controller is upgraded. The shutdown upgrade method takes the storage devices

offline for a period of time while the software is upgraded simultaneously on both

controllers.

Before initiating an ACS rolling upgrade, please refer to the HSG80 ACS Solution

Software Version 8.7 Installation and Configuration Guide for additional instructions.

These procedures include consideration for Solution Software, Secure Path Software

and switch firmware, as well as controller-based upgrade. Specific instructions for the

Solution Software and the proper sequence for all components is included.

NOTE: Rolling upgrades from ACS Version 8.5 (or earlier) to ACS Version 8.7 are not

supported. In these cases, a shutdown upgrade is required.
