SavWareHA Administration Screen
Each mirror
will consist of a pair of mirror element boxes, the Primary System
shown on the left, and the Standby System shown on the right. Underneath
the mirror description (‘Mirror 0’ above) is shown the
device name (‘/dev/mirror00’ ), and its size (1461Mb).
The system status (‘Normal Operation’, ‘On stmain
’) is shown in the upper right hand corner of the screen.
SavWareHA Screen Definitions
Mirror Status Codes
The mirror status
codes are located in the upper right hand corner of each mirror
side’s display box. See the ‘Specific Error Recovery Procedures’
section in this manual for more information.
 |
|
| ACTIVE |
Mirror
is GOOD and in use. The mirror is currently mounted. |
|
|
| CHECK |
An unknown
error was encountered while getting the status of the mirror
. Usual indications are network or device errors or misconfiguration
of mirror devices. Removal and rebuilding of the mirror (not
SavWareHA itself), or testing of the network connection is the
suggested remedy. |
| COLD |
The element
data is valid as of the date displayed. The element can be updated
manually via the Regenerate Mirror option. Usually reserved
for either root mirrors or for inactive (archival) data mirroring. |
|
|
| DISK
ERROR |
A disk
error has been reported on the mirror device. The mirror has
been broken. Correct the hardware problem and regenerate the
mirror with the ‘Fix Broken Mirror: Regenerate Mirror’
selection. |
|
|
| ERROR |
An error
was encountered while trying to access the mirror device. Correct
the network communication error(s) and regenerate the mirror
with the ‘Fix Broken Mirror: Regenerate Mirror’ selection.
|
|
|
| GOOD |
Mirror
is GOOD but is not in use. The mirror is not currently mounted.
|
|
|
| MISMATCH
|
The date
& time codes are different on the mirror elements. This
usually occurs when some of the controlling files in either
‘/etc/default’ or ‘/etc/sentinel.d’ have
become corrupted; or may reflect misconfiguration of mirror
devices. Removal and rebuilding of the mirror (not SavWareHA
itself) is the suggested remedy. |
|
|
| NEED
REGEN |
Mirror
side requires regeneration . No reads are enabled on the destination
mirror element. |
|
|
| NOT
CLOSED |
The system
was not shutdown properly. The mirror must have ‘fsck ’
run on the mirror device after regeneration has started. Until
both regeneration and a successful ‘fsck’ has occurred,
the mirror will not be accessible. |
|
|
| NOT
SETUP |
The drive
has not been setup for a mirror . This usually means that the
SavWareHA configuration files expected to find a mirror stamp
on the device, but did not. |
