2. Complete the table below by filling in (1a) and (1b) as instructed.
Total No. /cms size in MB

3. Compare the figures in (1a) and (1b). They should be approximately
equal. The two will not correspond exactly, but they should be within
about 10% of the /cms size figure. A major discrepancy between the
disk space you should have and the space recognized by the
software usually indicates a connectivity problem. You can check
connectivity by checking the output of a metastat command to see
that all the disks are recognized. For example:
# metastat
