If you do not want to configure CHAP using BIOS, you can alter the iSCSI initiator properties
after the system is booted.
• If one-way CHAP was selected, enter the matching CHAP secret as follows:
root@jnodec103140:S99814# sethost initchap -f aaaaaabbbbbb EsxHost1
root@jnodec103140:S99814# showhost -chap
• If mutual CHAP was selected, enter the mutual CHAP secret as follows:
root@jnodec103140:S99814# sethost initchap -f aaaaaabbbbbb EsxHost1
root@jnodec103140:S99814# sethost targetchap -f bbbbbbcccccc EsxHost1
root@jnodec103140:S99814#
root@jnodec103140:S99814# showhost -chap
Id Name -Initiator_CHAP_Name- -Target_CHAP_Name-
1 EsxHost1 EsxHost1 S814
root@jnodec103140:S99814#
After entering the CHAP secret, exit the BIOS and reboot the host.
