STO-DATA (Stored Data)
NOTE:
STO-DATA problems can be caused by faulty MSS hardware or hardware
used to provide communication between active and standby SPEs. If
hardware errors are present for H-ADAPTER, TAPE, DISK, or DUPINT,
investigate those first and then run
test stored-data
to address file
inconsistencies.
The Mass Storage System (MSS) consists of the following components which are
part of the system’s SPE:
■ TN1656 Disk circuit pack
■ TN1656 Tape circuit pack
■ Host Adapter circuit located on the UN332 MSS/Network Control circuit
pack
Each disk and tape drive stores 2 copies of each of the following:
■ The software that the system runs (the ‘‘boot image’’)
■ Translation data
■ Software update data (also known as program updates or patches)
■ Announcement files from the TN750 Announcement circuit pack
■ File directory
■ Error log
■ In special circumstances, a core dump of all system memory (single copy)
The disk is the primary storage device. Files on disk are generally used to reboot
the system or to restore files that are lost or corrupted during a malfunction. The
tape is used to backup the disk and as a portable medium for data, such as is
used for introduction of a new software load.
In High and Critical Reliability systems (duplicated SPE) the tape and disk drives
are duplicated as part of the PPN control carrier, resulting in a total of 4 devices,
each storing 2 copies of the aforementioned files. Ideally, the files on all of the
devices are identical, but malfunctions or even normal operations can lead to
inconsistencies.
