Table 34 Linux failure scenarios (continued)
Failure effect Fault stimulus
Short: I/O suspended, possible data loss.
Long: I/O halts with I/O errors, data loss. HBA driver must be reloaded
before failed drives can be recovered, fsck should be run on any failed
drives before remounting. Server path failure
Short: I/O suspended, possible data loss.
Long: I/O halts with I/O errors, data loss. HBA driver must be reloaded
before failed drives can be recovered, fsck should be run on any failed
drives before remounting. Storage path failure
IBM AIX
Table 35 IBM AIX failure scenarios
Failure effect Fault stimulus
Check disk when rebooting. Data loss, data that finished copying survived Server failure (host power-cycled)
Short term: Data transfer stops. Possible I/O errors.
Long term: Repeated error messages in errpt output. System reboot causes
loss of data on disk. Must crfs disk. Switch failure (SAN switch disabled)
Short term: Data transfer stops. Possible I/O errors.
Long term: Repeated error messages in errpt output. System reboot causes
loss of data on disk. Must crfs disk. Controller failure
Short term: Data transfer stops. Possible I/O errors.
Long term: Repeated error messages in errpt output. System reboot causes
loss of data on disk. Must crfs disk. Controller restart
Short term: Data transfer stops. Possible I/O errors.

VMware
Table 36 VMware failure scenarios
Failure effect Fault stimulus
OS reboots, automatically checks disks. HSV disks must be manually
checked unless auto mounted by the system. Server failure (host power-cycled)
Short: I/O suspended, possible data loss.
Long: I/O halts with I/O errors, data loss. HBA driver must be reloaded
before failed drives can be recovered, fsck should be run on any failed
drives before remounting. Switch failure (SAN switch disabled)
Short term: I/O suspended, possible data loss.
Long term: I/O halts with I/O errors, data loss. Cannot reload driver,
need to reboot system, fsck should be run on any failed disks before
remounting. Controller failure
