problem adding second MD1000 enclosure to LSI 9200-16e
I have 15x SAS drives in a Dell MD1000 enclosure, attached to an LSI 9200-16e. This has been working well. The system is boothing off of internal drives, on a Dell SAS 6ir. I just tried to add a second storage enclosure, with 15 more SAS drives, and I got a lockup during Loading Kernel. I got the same results, whether I daisy chained the enclosures, or plugged them both directly into the LSI

Hi, We bought a new Dell PowerEdge 2950III with Perc 6/i and have the disk geometry problem using 6.3 final or 7.0 RC1.

Running on Dell hardware?
I have a Dell R710 which has been flaky for some time. It crashes about once per week. I have literally replaced every piece of hardware in it, and reinstalled Sol 10u9 fresh and clean. I am wondering if other people out there are using Dell hardware, with what degree of success, and in what configuration? The failure seems to be related to the perc 6i. For some period around the time

SAS/SATA DAS
I need to replace a slow HP MSA20 that's a bottleneck right now (We are an HP shop). HP's only option with 3.5" SATA drives is stuck at SATA I behind a SAS controller. Dell makes an MD1000 that claims SATA II speeds behind a SAS Perc 5/E (Don't know anything about dell). Anyone got any real world info they can share? I need 3.5" SATA II at least 12 drives behind SAS, I am

IO causing major performance issues
Hello everyone. I'm wondering what other people's experiences are WRT systems becoming unresponsive (unable to ssh in, etc) for brief periods of time when a large amount of IO is being performed. It's really starting to cause a problem for us. We're on Dell PowerEdge 1955 blades - but this same issue has caused us problems on PE1950, PE1850, PE1750 servers. We're running

what is difference between "slow initialize" and "patrol read" on RAID?
We have DELL server with MD1000 Disk array in it. O.S. is CENTOS 5.5. Recently every time MD1000 "patrol read" start I will get "media error" messages on /var/log/message file. I use MD1000 "slow initialize" to initialize "bad disk" and NO error. After "slow initialize" finish, I manually "startup patrol read". I continue get

write-back cache question
I have a perc5i (and perc5e) raid controller in my poweredge 2970 running centos 5.5. The RAID controller config is set for write-back policy, which I can confirm by checking in OpenManage. I also called Dell and ran their reporting application and had them double check to make sure everything looks OK hardware wise and they confirm that it does Yet when CentOS boots is appears to use the

OT: LSI SAS1068e / Perc6/iR RAID Health
Is anybody here monitoring Dell SAS6/iR RAID health? I have a mix of CentOS 5.9 and 6.3 installs on the PE1950s. I'm finding drivers and Megaraid Storage Manager downloads via LSI's site, but I'd prefer not to install a bunch of crapware. All I need is the proper LSI daemon which exports info via SNMP. I've used check_sasraid_megaraid Nagios script [0] in the past for PERC5i and

Xen 3.3.1 Windows HVM Disk I/O -> domU and dom0 hangs
Hi, we are currently working on getting windows working on your xen servers. but we are facing a severe problem where dom0 and all domus hang for 1-5 seconds from time to time. we think it is probably because of disk i/o, because top sometimes says 100% wa (waiting on io) during the hang. dom0 has cpu 0 for exclusive use and the windows vms use cpu 1 to 7. should we give dom0 more than once
