Mpt raid event notification
Hi,
We have a Sun X4100 with Freebsd 6-Stable i386 with a LSI 1064 disk
controller,that uses the mpt driver.
The machine uses two HD SAS 73GB in RAID 1.
The RAID 1 works fine, but the event notification is incomplete and there is
no way to know the status of the RAID, if the status is optimal, degraded or
is Re-Syncing.
We have added in the MPT_CAM.C at the funtion
mpt_cam_event(struct mpt_softc *mpt, request_t *req,MSG_EVENT_NOTIFY_REPLY
*msg)
this code :
case MPI_EVENT_INTEGRATED_RAID:
{
switch ((msg-Data[0] 16)
0xff) {
case
MPI_EVENT_RAID_RC_VOLUME_CREATED :
mpt_prt(mpt,
Integrated Raid: Volume Created\n);
break;
case
MPI_EVENT_RAID_RC_VOLUME_DELETED :
mpt_prt(mpt,
Integrated Raid: Volume Deleted\n);
break;
case
MPI_EVENT_RAID_RC_VOLUME_SETTINGS_CHANGED :
mpt_prt(mpt,
Integrated Raid: Volume Settings Changed\n);
break;
case
MPI_EVENT_RAID_RC_VOLUME_STATUS_CHANGED :
mpt_prt(mpt,
Integrated Raid: Volume Status Changed\n);
break;
case
MPI_EVENT_RAID_RC_VOLUME_PHYSDISK_CHANGED :
mpt_prt(mpt,
Integrated Raid: Volume Physdisk Changed\n);

}
break;
}
This code tell us that the volume status of the raid has changed,but no the
actual state of the volume (optimal,degraded),and we have no idea how to add
this funcionality in the driver.
Anybody know how to modify the driver to know the actual state of the RAID
volume.

Which one is best MTA for me? We (one of the largest ICP company in China and provides some billions of free e-mail accounts) has replaced our locally hacked qmail with postfix in 2005. I and one of our sys-op has accomplished all of the necessary migration work (coding to re-implement our features, testing, and migration itself) within three weeks, so once you have confirmed what your requirement is, it's not very hard to do. I do not want to say simply that you will want postfix, but I would like to explain the reasons why we have did the migration: - Performance. qmail uses about 3 times of file I/O operation for each mail delivery, compared with postfix. For a busy MX server this means that you have to prepare more servers to do the same job. - Features. Most of extension to qmail has to be done by patching. It's true that there is a lot of qmail patches floating around, but you have to carefully maintain a local qmail tree. Postfix has a lot of built-in anti-spam and other features, and it is relatively easy to implement new feature with Python/Twisted through Postfix's interface - no patch needed for postfix itself. - Manageability. Our system administration team used to be very familiar with qmail. However, for large ISP/ICPs, qmail fails to solve the following essential problems that postfix does not have: - Hard to reconstruct mail queue after damage In postfix this can be done with 'postfix check'. - Have to watch its queue situation Once you got the queue stuck with a lot (200,000+) e-mails that can not be delivered temporarily, e.g. due to a backend hardware issue, all e-mails would be delivered very slowly, and incoming e-mail would make the situation worse. We used to have a monitoring script that adds an ipfw rule to block all subsequent incoming mail to work around this issue. With postfix, stuck e-mails are stored in separate queue. - and a lot more... - Maintainability. Extending postfix for your own need is easy, our new anti-spam system is primarily written as a policy/filtering/table lookup daemon with Python/Twisted, making the code much more easy to understand and maintain. It's not easy for someone to be able to pick up the qmail patch due to the coding style and lack of comments. More importantly, postfix is being actively maintained, but qmail is not. I'm not sure about the problem you are having. If you are going to set up a new mail server (cluster) then don't use qmail, it would be a nightmare if your system grows. Postfix is a good choice, and there are some other choices, e.g. sendmail, exim, etc. Cheers, -- Xin LI [EMAIL PROTECTED] http://www.delphij.net/ FreeBSD - The Power to Serve! signature.asc Description: OpenPGP digital signature
