Firmware Upgrades when Using RE
Redundant Electronics Overview
B-3
■
SLC and CLI connections are terminated. You must re-establish connections to the
library using the IP address or DNS alias of the new active library controller (the
former standby controller).
Factors that Prevent an RE Switch
■
The standby library or drive controller is in a fault or eject state.
■
The standby code is not running on the standby library or drive controller cards.
■
A firmware download or card initialization is in progress.
Factors that Initiate an Automatic Failover
An automatic failover can be initiated by either the active or standby library controller.
The active library controller initiates an automatic failover when:
■
Its partner drive controller card is not installed or it is not communicating.
■
It detects a catastrophic internal software error.
The standby library controller initiates an automatic failover if the active controller is
not functioning normally.
Ways to Initiate a Manual Failover
■
Host tape management
(ACSLS or ELS) — Failover can be initiated from either
the active or standby library controller. The standby library controller accepts only
set host path group
and
force switchover
HLI requests.
■
SLC
— Failover is initiated from the active library controller only (see
■
CLI
— Failover can be initiated from either the active or standby library controller.
This function is only available to Oracle support representatives.
You may want to perform a manual switch after initial installation of the standby
cards, after a firmware upgrade, or periodically to check that the failover function is
working properly. It is not possible to manually switch the library controllers without
the drive controllers — the controllers are always switched as a pair.
Firmware Upgrades when Using RE
Firmware upgrades for libraries with RE are minimally disruptive to library
operations. You can load and unpack new code simultaneously on the active and
standby controller cards and on all devices. The code is then activated, and the active
and standby controllers and most devices are re-initialized. Under most circumstances,
robot initialization is bypassed.
The loading, unpacking, and activation of code are not disruptive to library operations
until the library is rebooted. During the reboot process (which takes approximately 10
minutes), the HLI host applications (ACSLS and ELS) queue all mount and dismount
Note:
Before initiating a manual switch, you should verify that the
standby library and drive controllers are running normally (see
