NetWare
Table 31 NetWare failure scenarios.
Failure effect Fault stimulus
OS reboots. When mounting volumes, volume repair or NSS rebuild
executes to cleanup volumes. Data loss, data that finished writing
survived.
Server failure (host power-cycled)
I/O to device stops with I/O errors indicated on server console.
Applications using lost connection halts. Server restart recommended
but may not be necessary. Volume repair or NSS rebuild runs when
volumes are mounted.
Switch failure (SAN switch disabled)
I/O to device stops with I/O errors indicated on server console.
Applications using lost connection halts. Server restart recommended
but may not be necessary. Volume repair or NSS rebuild runs when
volumes are mounted.
Controller failure
I/O to device stops with I/O errors indicated on server console.
Applications using lost connection halts. Server restart recommended
but may not be necessary. Volume repair or NSS rebuild runs when
volumes are mounted.
Controller restart
I/O to device stops with I/O errors indicated on server console.
Applications using lost connection halts. Server restart recommended
but may not be necessary. Volume repair or NSS rebuild runs when
volumes are mounted.
Server path failure
I/O to device stops with I/O errors indicated on server console.
Applications using lost connection halts. Server restart recommended
but may not be necessary. Volume repair or NSS rebuild runs when
volumes are mounted.
Storage path failure
Linux
Table 32 Linux 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
