1. Display available disk space by entering a
df -k
command. The
system responds with a file system table. For example:
The figures on the
/dev/md/dsk/d21
line are critical. You will use
them to determine whether
Solstice DiskSuite
*
is administering all
your disks.
2. Complete the table below by filling in (1a) and (1b) as instructed.
3. Compare the figures in (1a) and (1b) of the table. 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 your
Solstice DiskSuite
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:
Filesystem kbytes used avail capacity Mounted on
/dev/md/dsk/d13 1039555 355366 580239 38% /
