6
Start the regedit32 and add a DWORD value in the following
Registry key:
\\HKEY_LOCAL_
MACHINE\SYSTEM\CurrentControlSet\Services\aic78
xx\Parameters\Device0\MaximumSGList
7
Use the following formula to calculate the value of the
MaximumSGList:
MaximumSGList = (BlockSize/4096)+1
For example, the MaximumSGList value for a 256k block size is 65, as
follows:
MaximumSGList = (265k/4k) + 1 = 64 + 1 = 65
If you have, for example, three aic78xx based SCSI channels on your
system, change the appropriate ...\Device0, ...\Device1 or ...\Device2
value. If you want to set all adapters at the same time, specify
MaximumSGList for ...\Device\.... Omitting the numerical reference
sets the value for all aic78xx adapters.
The block size can also be changed using the Data Protector management
interface.
1
To do this, select the Devices & Media option from the drop down
list.
2
Right click on a discovered tape device and select Properties.
3
Select the Settings tab and then click on the Advanced button.
4
Select the Sizes tab and from here the block size can be modified as
shown in
figure 65
below.
