Table 57 HP-UX failure scenarios (continued)
Failure effect Fault stimulus
Short term: Data transfer stops. Possible I/O errors.
Long term: Job hangs, cannot umount disk, fsck failed, disk corrupted,
need mkfs disk. Server path failure
Short term: Data transfer stops. Possible I/O errors.
Long term: Job hangs, replace cable, I/O continues. Without cable
replacement job must be aborted; disk seems error free. Storage path failure
Windows Server
Table 58 Windows Server failure scenarios
Failure effect Fault stimulus
OS runs a command called chkdsk when rebooting. Data lost, data that
finished copying survived. Server failure (host power-cycled)
Write delay, server hangs until I/O is cancelled or cold reboot. Switch failure (SAN switch disabled)
Write delay, server hangs or reboots. One controller failed, other
controller and shelves critical, shelves offline. Volume not accessible.
Server cold reboot, data lost. Check disk when rebooting. Controller failure
Controller momentarily in failed state, server keeps copying. All data
copied, no interruption. Event error warning error detected during paging
operation. Controller restart
Write delay, volume inaccessible. Host hangs and restarts. Server path failure
Write delay, volume disappears, server still running. When cables
plugged back in, controller recovers, server finds volume, data loss. Storage path failure
