nn
—The PowerVault 700N storage system
enclosure address number. This message
appears when the system detects an error
on one or more Dell PowerVault 700N
storage systems. Check the LEDs of the
specified Dell PowerVault 700N storage
systems to see whether a fan or power
supply needs to be replaced. Replace the
faulty fan or power supply on the Dell
Power-Vault 700N storage system, if
needed.
Maintenance mode The system is running in maintenance
mode. Refer to the
Dell PowerVault 720N,
740N, and 760N System Administrator and
Command Reference Guide
for more
information about maintenance mode.
Non Maskable interrupt This message is usually generated by a
correctable (nonfatal) memory error, but
might signal other conditions.
If this message appears repeatedly, it
might indicate a defective memory mod-
ule (DIMM). Refer to the console
messages or to the
/etc/messages
file for
detailed information.
NFS service not enabled This message appears only if you have
licensed NFS. NFS service has been dis-
abled either because the system failed to
enable it when it started, or because you
disabled it with the nfs off command.
Parity disk is broken The parity disk is not operating and the
system is in degraded mode. The solution
depends on whether a hot spare is
installed in the system. Refer to the
Dell
PowerVault 720N, 740N, and 760N System
Administrator and Command Reference
Guide
for information about replacing a
faulty disk.
