STO-DATA (Stored Data)
NOTE:
STO-DATA problems can be caused by faulty MSS hardware or hardware
used to pro vide c ommu nicat ion be tween activ e and stand by SPEs. I f
hardware errors are present for H-ADAPTER, TAPE, DISK, or DUPINT,
investigate those first and then run test store d-data to address file
inconsistencies.
The Mass Storage System (MSS) consists of the following components whic h are
part of the system ’s SPE:
■TN1656 Disk circuit pack
■TN1656 Tape circuit pack
■Host Adapter circuit loc ated on the UN332 MSS/Network Control circuit
pack
Each disk and tape d rive stores 2 copies of each of the follo wing:
■The software that the system runs (the ‘‘boot image’’)
■Translation data
■Software update data (also known as prog ram updates or patches)
■Announcement files from the TN750 Announcement c ircuit pack
■File d irect ory
■Error log
■In special circ umstances, a core dump of all s ystem memory (single copy)
The disk is the primary storag e device. Files on disk are gene rally used to reboot
the system or to restore files that are lost or corrupted during a malfunction. The
tape is used to bac kup the disk and as a p ortable medium for data, suc h as is
used for introduction of a new software load .
In Hig h and Criti cal Rel iabi lity sy stems ( dup licat ed SPE) th e tap e and d isk d rives
are duplicated a s part of the PPN control carrier, resulting in a total of 4 d evices,
each storing 2 cop ies of the aforementioned files. Ideally, the files on all of the
devices are identic al, but malfunctions or even normal op erations can lead to
inconsistencies.
