Preparing the Host System
3–20 HSG80 ACS Solution Software Version 8.7 for Compaq Tru64 UNIX Installation and
Configuration Guide
To rescan the bus on Tru64 Version 4.x systems, type the following:
# scu scan edt
# scu show edt
9. Restart I/O (applications).
10. Start Client.
New Features, ACS 8.7 for Tru64
The following are new features implemented in ACS 8.7 for use by the Tru64
operating system:
• “Host Connection Table Management Improvements” on page 3–20
• “Selective Management Presentation” on page 3–25
• “Linking WWIDs for Snap and Clone Units” on page 3–28
• “SMART Error Eject” on page 3–30
• “Error Threshold for Drives” on page 3–34
Host Connection Table Management Improvements
Current implementation of host connectivity grants access to the first ninety-six (96)
host connections that attempt to login to the controller. After that, all edits to the host
connection table are manual and require extensive CLI commands to delete and/or
replace connections.
Host Connection Table Locking
Host table lock and unlock commands have been added to control the connection table
in NVRAM. When the table is locked, the host login request (PLOGI) will be rejected
(unless the connection is already in the table) and the request will be stored internally
on a rejected hosts table. In the default mode, if a PLOGI is received when the
connection table is unlocked, the connection will be granted if there is room in the
connection table. The lock state can be changed with the following CLI commands:
CLI> SET <THIS | OTHER> CONNECTIONS_LOCKED
CLI> SET <THIS | OTHER> CONNECTIONS_UNLOCKED
The CONNECTIONS_LOCKED and CONNECTIONS_UNLOCKED switches must
be typed completely to stop someone from inadvertently changing the state of the
lock.
