Tivoli Storage Manager for Windows Administrator's Reference
Specifies how mirrored volumes are to be accessed when the server reads a
recovery log or database page during normal processing. The defaults
are:
mirrorread log normal
mirrorread db normal
Syntax
>>-MIRRORRead----+-LOG-+---+-Normal-+--------------------------><
'-DB--' '-Verify-'
Parameters
- LOG
- Specifies that this is the mode to be used for reading recovery log
pages.
- DB
- Specifies that this is the mode to be used for reading database
pages.
- Normal
- Specifies only one mirrored volume is read to obtain the desired
page. This is the default.
- Verify
- Specifies that the server read all mirror volumes for a page every time a
recovery log or database page is read. If an invalid page is
encountered on a mirror volume, it is automatically re-synchronized with valid
contents from another mirror volume. This mode decreases server
performance since each mirror volume for the page is accessed on every
read.
Examples

recovery log or database page is read:
mirrorread log verify
mirrorread db verify
