Troubleshooting Resources 4–11
Host’s log file or
maintenance terminal
indicates that a forced
error occurred when the
controller was
reconstructing a RAIDset
or mirrorset.
Unrecoverable read errors
may have occurred when
controller was
reconstructing the
storageset. Errors occur if
another member fails
while the controller is
reconstructing the
storageset.
Conduct a read scan of the
storageset using the
appropriate utility from the
host’s operating system,
such as the “dd” utility for a
TRU64 UNIX
®
(formerly
DIGITAL UNIX) host.
Rebuild the storageset, then
restore its data from a
backup source. While the
controller is reconstructing
the storageset, monitor the
host error log activity or
spontaneous event reports
on the maintenance terminal
for any unrecoverable errors.
If unrecoverable errors
persist, note the device on
which they occurred, and
replace the device before
proceeding.
Host requested data from
a normalizing storageset
that didn’t contain the
data.
Use the SHOW
storageset-name
command
to see if all of its members
are “normal.”
Wait for normalizing
members to become normal,
then resume I/O to them.
