Re: centos 5.3 crc32c module question

Hi Charles,

If you are just using CentOS as the initiator and not the target then you could always use iscsi-initiator-utils (a.k.a. open-iscsi) instead of ofed. This is supported in the official CentOS repos. You just need to

 yum install iscsi-initiator-utils
 iscsiadm -m discovery -p <targetip> -t sendtargets
 iscsiadm -m node -p <targetip> -T <target iqn reported by prev cmd> -l

Then the block device nodes appear - as if by magic - under /dev/disk/by-path/

I'm not familiar with ofed, but it sounds like it requires you to reconfigure and rebuild your kernel.

Regards,

Alex

Hi, I am using centos 5.3 (kernel 2.6.18) + ofed 1.4 as my initiator, when I
try to login on iscsi target, there's following errors in the initiator
side:
iscsi: registered transport (tcp)
scsi5 : iSCSI Initiator over TCP/IP
 connection4:0: Could not create connection due to crc32c loading error.
Make sure the crc32c module is built as a module or into the kernel
 session4: couldn't create a new connection.<6>scsi6 : iSCSI Initiator
over TCP/IP

I am able to run thru the same procedure on ubuntu 8.04 (kernel 2.6.24).

There's no crc32c.ko and libcrc32c.ko under /lib/modules.
Any ideas on how can I get it run on my current centos 5.3 box?
Thanks for your help.
Thanks,
Charles
