That should say below, we are using Powerpath on the CX300's AND the CX600's... ----------------------------------------------------------------------- We are using Powerpath with CX300's and Emulex HBA's, also with OCFS on Red Hat 2.1 AS. Kernel upgrades are the biggest issue that we have, as some of the drivers are dependent on modules built for specific kernels, and if your

Is anyone using CentOS 4.4 with an EMC Clariion SAN? In particular, I want to know if PowerPath and Naviagent will work on a CentOS 4 system connected to a san using Qlogic or Emulex cards. I tried a couple years ago with Fedora Core 1 or 2, and couldn't get the kernel modules from PowerPath to work since the kernel wasn't the official RHEL one. I'm most interested in

Hi, We had received a new EMC storage (Clariion CX4) and the EMC analist has told us that CentOS aren't on their support list, but RHEL are :) Well anybody on the list has a CentOS host talking (iSCSI) with an EMC storage, preferably using the EMC Powerpath software, and can talk about you experience? Or I will need to buy some REHL licenses ? I'll put my hands on it only next

How much fun can you have with a simple thing like powerpath? Here''s the story: I have a (remote) system with access to a couple of EMC LUNs. Originally, I set it up with mpxio and created a simple zpool containing the two LUNs. It''s now been reconfigured to use powerpath instead of mpxio. My problem is that I can''t import the pool. I get: pool: ###### id:

On some machines running PowerPath, there''s sometimes issues after an update/upgrade of the PowerPath software. Sometimes the pseudo devices get remapped and change names. ZFS appears to handle it OK, however sometimes it then references half native device names and half the emcpower pseudo device names. So the SA can easily be confused. Is there a way to tell ZFS which device names

If anyone is running this configuration, I have some questions for you about Page83 data errors. This message posted from opensolaris.org

I used this command to create volume label on OCFS: mkfs.ocfs -F -b 128 -L data13 -m /oradata/data13 -u oracle -g dba -p 0775 /dev/emcpowerp1 emcpowerp is composed of /dev/sdad and /dev/sdk. It seems the above command created the same labels for /dev/emcpowerp1, /dev/sdad1 and /dev/sdk1. But when I tried to mount this ocfs filesystem by label, it gave me the following error. # mount -L data13

Hi there, have a strange behavior if i?ll create a zfs pool at an EMC PowerPath pseudo device. I can create a pool on emcpower0a but not on emcpower2a zpool core dumps with invalid argument .... ???? Thats my second maschine with powerpath and zfs the first one works fine, even zfs/powerpath and failover ... Is there anybody who has the same failure and a solution ? :) Greets Dominik

Hi all, I'm troubleshooting an ocfs2 performance problem where creating files in a directory containing ~180k files is taking significant time to complete. Sometimes creating an empty file will take >100 seconds to complete. This is a three node cluster. I'm currently running OCFS2 1.2.3-1. Are there any changes in a recent version that may address this issue? What should I look

OEL 5, OCFS 1.4, using EMC Power Path for multi pathing. I want t mount the OCFS2 file system on the emc power path device. I can mount by UUID, and not have to worry about persistent bindings across nodes. But how do I make sure when it mounts by UUID , that the pwoer path device is used. Any help will be much appreciated. Thanks -- Sridhar Avantsa savantsa at gmail.com -------------- next

I've been reading this group for a while and I've noticed a variety of comments regarding running OCFS on top of path-management packages such as EMC's Powerpath, and it brought to mind a problem I've been having. I'm currently testing a six-node cluster connected to a Hitachi 9570V SAN storage array, using OCFS 1.0.12. I have six LUNs presented to the hosts using HDLM,

I was curious if someone on this list has performance numbers with and without PowerPath 3.0.3 on RH AS 2.1 Oracle 9i RAC systems with OCFS. I know that there were some concerns with PowerPath intercepting IO's and slowing performance related to OCFS. Appreciate your feedback. Raj

For those customers that are on this list and are using EMC Powerpath or HP Securepath and have performance problems while using ocfs and point to ocfs first. the actual io overhead for an io on ocfs compared to raw, when it's database io is negligable, we don't do any locking, we have about 40000 clockticks of processing from logical to physical offset, nothingin todays cpu world.

Hello All. I'm working on building support for the Clariion range of standby power supplies. I've found you can get hold of these easily on ebay like: http://www.ebay.co.uk/itm/EMC-CLARiiON-Standby-Power-Supply-118031985- SPS-1000W-/160373295258 There is a problem that I haven't been able to work around. After 90 seconds without power, the device shuts down. This is because
