2. Verify that there is sufficient swap space to dump memory. Type the swap -l command. # swap -l swapfile dev swaplo blocks free /dev/dsk/c0t3d0s0 32,24 16 4097312 4062048 /dev/dsk/c0t1d0s0 32,8 16 4097312 4060576 /dev/dsk/c0t1d0s1 32,9 16 4097312 4065808 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. # 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. 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. 218 Sun Fire V445 Server Administration Guide • August 2006
4. Type the df -k1 command to identify locations with more space. # df -k1 Filesystem kbytes used avail capacity Mounted on /dev/dsk/c1t0d0s0 832109 552314 221548 72% / /proc 0 0 0 0% /proc fd 0 0 0 0% /dev/fd mnttab 0 0 0 0% /etc/mntab swap 3626264 16 362624 81% /var/run swap 3626656 408 362624 81% /tmp /dev/dsk/c1t0d0s7 33912732 9 33573596 1% /export/home 5. Type the dumpadm -s command to specify a location for the dump file. # dumpadm -s /export/home/ Dump content: kernel pages Dump device: /dev/dsk/c3t5d0s1 (swap) Savecore directory: /export/home Savecore enabled: yes The dumpadm -s command enables you to specify the location for the swap file. See the dumpadm (1M) man page for more information. Testing the Core Dump Setup Before placing the system into a production environment, it might be useful to test whether the core dump setup works. This procedure might take some time depending on the amount of installed memory. Back up all your data and access the system console. See: ■ “About Communicating With the System” on page 24 ▼ To Test the Core Dump Setup 1. Gracefully shut down the system using the shutdown command. 2. At the ok prompt, issue the sync command. You should see “dumping” messages on the system console. The system reboots. During this process, you can see the savecore messages. Chapter 9 Troubleshooting 219
