I have heard of dump? The binary RPMs created by the source RPMs here do not do these things, they only build the driver module and initrd image. Are you new to LinuxQuestions. Non non-free firmware required! I’m going to give that a thorough read this weekend. I’ll check also one of our machine, to see if i can reproduce this behavior or not. I would like to include to to do diagnostic on the hard drives and maybe turn off the cache in the hard drive to keep data consistent and keep the data moving throughly.

HP Smart Array CCISS driver
They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own. Firmware updates weren’t as important back then, so you’re probably not going to gain much from running updates. As stated read performance seems very poor to me, because all data should be send from cache which means there should be nearly no differences between buffered or cached reads.
Your distribution may differ.
HP ProLiant Servers
Use these for systems using 2. This could solve the whole issue about the slow disk speed. Also, auf Englisch jetzt Adding a BBU solved it for me. A new Smart Array driver called “hpsa” has been accepted into the main line linux kernel as of Dec 18,in linux If it is, then you should have a lot more bandwidth such as at least 60 megabytes per second.
Hi, the backup battery unit is esssential for the RAID controller because smzrt will go in read cache only mode without this, smarf all write requests will be done directly to disks what slows down all activity of the controller.
Running a quick test on my DL36t0 G3 looks like its going to be easier and better to install all the HP management agents. The system would panic when deleting many arrah volumes at one time.
After installation and boot from internal storage some fixes: I’m not the oldest or wisest sysadmin around. P Thanks all for your help in this thread, very much appreciated. Fixed a panic that could arise during an insmod and rmmod of the cciss driver. The binary RPMs created by the source RPMs here do not do these things, they only build the driver module and initrd image.
Remember, this server went end-of-life in orso it’s a decade old.
I’ll check also one of our machine, to see if i can reproduce this behavior or not. I have heard of dump? It reports any status changes, like failing disks, to the syslog and optionally to a remote host using SNMP traps. Worked fine, no firmware required. Thanks all for your help in advance and for keeping a great community!
This will prevent from updating the inode atime information on every read access, this will speed up all operations on the files. There may be other software designed to work with cciss e.
And associated tape wear I’m not looking neccessarily for someone to tell me a full solution but the way things are looking, its going to be a case of buying another server with a big RAID 0 striped array on it and thrash everything to there, once staged on there I can back up to tape nice and fast.
