Study Notes

Last week one of Tyan platforms failed after running 15 hours, our engineer investigated in this issue and reported we have to replace and re-configure it. As Zhufeng went to Beijing, Gavin told me to fix this issue and repair the relationship with UT customer. In UT, I add the new nodes. There’re two things we should care in the future:

1. Configure the DNS reserve setting. To verify the current settin, execute the following command to resolve the host, in my case:
# host 172.23.5.6
# host 172.23.5.7
Above two return the strings “ba880.nas_ba880.uit”.
# host ba880.nas_ba880.uit
It should return the correct IP addresses, 172.23.5.6 and 172.23.5.7.

2. Configure the /etc/iscsi.con”f and /etc/initial.conf. make sure the /etc/initial.conf lines is as same as the key in BS3000(storage devices). Because the former one has the right setting it can find the iscsi devices,(# iscsi-ls), I just copy its /etc/iscsi.conf and /etc/inital.conf to the new added nodes, then restart the iscsi service.
