Hi Bret, thanks for your reply.
I guess yes, the sp_configure "disable disk mirroring" has following output:
1> sp_configure "disable disk mirroring"
2> go
Parameter Name Default Memory Used Config Value
Run Value Unit Type
------------------------------ ----------- ----------- ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- -------------------- --------------------
disable disk mirroring 1 0 0
0 switch static
(1 row affected)
(return status = 0)
And there are some other devices using mirror per the output of sp_helpdevice:
log_mir1 /opt/sybase/devices/log1/S1_log_mir1.dat file system device, special, MIRROR ENABLED, mirror = '/opt/sybase/devices/data1/log_mir1.mir', serial writes, dsync off, directio on, reads mirrored, default disk, physical disk, 100.00 MB, Free: 0.00 MB 739 0 27 0 51199
log_mir2 /opt/sybase/devices/log1/S1_log_mir2.dat file system device, special, MIRROR ENABLED, mirror = '/opt/sybase/devices/data1/log_mir2.mir', serial writes, dsync off, directio on, reads mirrored, default disk, physical disk, 100.00 MB, Free: 100.00 MB 739 0 28 0 51199
log_mir3 /opt/sybase/devices/log1/S1_log_mir3.dat file system device, special, MIRROR ENABLED, mirror = '/opt/sybase/devices/data1/log_mir3.mir', serial writes, dsync off, directio on, reads mirrored, default disk, physical disk, 100.00 MB, Free: 100.00 MB 739 0 29 0 51199
Where I can find such statement in official documentation on the limit of unmount with mirroring. And could you please tell me how to turn off mirroring on this server?
