what is the block size?
what are the maximum number of blocks that can be read in one read?

df -g displays the block size of a file system as I have just discovered.

hi,

Information for PA400 can be found using saconfig command. Find the device file with "ioscan -fnkd ciss". Then display current configuration for the card using "saconfig /dev/ciss0" (if ioscan said device was /dev/ciss0).

Regards,

Fred

ls -s file name ( It gives the size of the files in blocks)

Thanks
