Question 3

Your server hangs intermittently and you believe it may be due to either faulty hardware or a driver. The support technician has told you to generate a live core dump of all memory pages for further analysis Your dump configuration is:

Dump content: kernel pages

Dump device: /dev/zvol/dsk/rpool/dump (dedicated)

Savecore directory: /var/crash

Savecore enabled: yes

Save compressed: on

You don't have enough space on the current dump device, so you need to store the dump on /dev/zvol/dsk/pool2/dump

Which option would you select to change the dump location for the next core dump and capture the content of all memory pages as requested by the support technician?

Adumpadm -d /dev/zvol/dsk/pool2/dump

Bdumpadm -d /dev/zvol/dsk/pool2/dump -c all

Cdumpadm -d /dev/zvol/dsk/pool2/dump -c curproc

Ddumpadm -s /dev/zvol/dsk/pool2/dump -c all
