The GUI indicates alarm status for the storage subsystem as follows:
v
Alarm control (enabled/disabled)
v
Alarm state (inactive/sounding/muted)
The GUI provides the following alarm controls for the storage subsystem:
v
Enable/disable alarm. (Error status is displayed if an attempt is made to enable
an alarm that is not present.)
v
Mute alarm.
The alarm sounds and the Overall Configuration Needs Attention turns on when one
of the following conditions occur:
v
Hardware malfunction in a storage subsystem – This includes an overheating
condition or a component failures (controllers, power supplies, or fans).
v
Transmission failures – This includes I/O transmission problems with the SFP
modules or cables.
When a subsystem failure is detected after the alarm has been enabled, the alarm
sounds until one of the following occurs:
v
The alarm is muted using the DS Storage Manager Subsystem Management
window GUI.
v
The alarm is muted using the Mute button on the interconnect-battery unit.
v
The problem that is indicated by the lit Overall Configuration Needs Attention
LED is resolved.
If the alarm sounds, check the storage subsystem for faults. For troubleshooting
procedures, see “Troubleshooting the storage subsystem” on page 142.
Installing the DS Storage Manager client
Refer to the
IBM System Storage DS Storage Manager Installation and Host
Support Guide
for the appropriate operating system for instructions on how to install
the Storage Manager software. Use that document and the online help to configure
the logical drives, partitions, and so on for the RAID controllers. Use your operating
system documentation to make the new logical drives accessible to the operating
system. Do not proceed with the configuration setup until you have completed the
DS Storage Manager installation.
Assemble any additional items in preparation for software installation. These items
might include the following:
v
HBA drivers.
v
Controller firmware version listed at the IBM DS5100 and DS5300 System
Storage Support Web site:
www.ibm.com/systems/support/storage/disk
v
IP addresses for RAID controllers (for out-of-band management only).
v
Additional documentation for switches and HBAs, if needed.
v
DS Storage Manager Support
CD, which includes the storage subsystem
controller firmware.
v
The DS5100 and DS5300 controller firmware should be updated to the correct
version. See “Software and hardware compatibility and upgrades” on page 23 for
version information. The latest level of DS5100 and DS5300 controller firmware
is available for download from the IBM support Web site for DS5100 and DS5300
storage products.
