2. Verify that there is sufficient swap space to dump memory. Type the swap -l
command.
TABLE 9-3
# swap -l
swapfile
/dev/dsk/c0t3d0s0
/dev/dsk/c0t1d0s0
/dev/dsk/c0t1d0s1
To determine how many bytes of swap space are available, multiply the number
in the blocks column by 512. Taking the number of blocks from the first entry,
c0t3d0s0, calculate as follows:
4097312 x 512 = 2097823744
The result is approximately 2 Gbytes.
3. Verify that there is sufficient file system space for the core dump files. Type the
df -k command.
TABLE 9-4
# df -k /var/crash/'uname -n'
By default the location where savecore files are stored is:
/var/crash/'uname -n'
For instance, for the mysystem server, the default directory is:
/var/crash/mysystem
The file system specified must have space for the core dump files.
If you see messages from savecore indicating not enough space in the
/var/crash/ file, any other locally mounted (not NFS) file system can be used.
Following is a sample message from savecore.
TABLE 9-5
System dump time: Wed Apr 23 17:03:48 2003
savecore: not enough space in /var/crash/sf440-a (216 MB avail,
246 MB needed)
Perform Steps 4 and 5 if there is not enough space.
