Figure 4.41 Raidvchkscan Command Example with -v offset Option

Output of the raidqvchkscan command with -v offset option:

„

Bsize: This column displays the data block size of Oracle I/O, in units of bytes.

„

STLBA: Displays the Start of LBA on a target volume for checking, in units of 512 bytes.

„

ENLBA: Displays the End of LBA on a target volume for checking, in units of 512 bytes.

Note: If STLBA and ENLBA are both zero, this means to check all blocks.

„

BNM: Displays the number of bits for checking regarding CHK-F2, in units of bits.
If BNM is zero, this means the checking for CHK-F2 will be disabled.
