The use of binary-only Linux kernel modules or drivers on the same server as SAP software is not recommended by SAP. SAP Note 784391 - SAP support terms and 3rd-party Linux Based on the volume layout on the array members, the dm-switch module routes each I/O to the optimal path within the PS Series group. A loadable kernel module, dm-switch, which implements a new Device Mapper target to the multipath devices. It also gathers information on the volume layout from the PS Series group.Ģ. Running in the background, the ehcmd daemon uses the Open-iSCSI management tool (iscsiadm) to add, remove, or modify iSCSI sessions to maintain an optimal number of iSCSI sessions. The EqualLogic Host Connection Manager daemon, ehcmd, which monitors the iSCSI session state and the configuration of the Linux server and PS Series group. The Dell EqualLogic HIT/Linux MPIO software consists of two components:ġ. Otherwise, the installation script loads the Dynamic Kernel Module Support (DKMS) package and compiles the Dell EqualLogic-supplied kernel module."ĮqualLogic Integration: Installation and Configuration of Host Integration Tools for Linux – HIT/Linux From the documentation "Installs a compatible prebuilt kernel module, if available.

My understanding is that the Equallogic MPIO driver will provide a faster, more efficient, connection to the SAN along with additional features. I understand that there are restrictions on using third party kernel modules.
Is the Equallogic SAN supported in Linux when using the HIT Kit to provide MPIO and snapshot support? The article from thorsten.staerk describes Equallogic SAN + Linux + native iSCSI (no mention of the HIT Kit). I closed SAN HQ, deleted the folder C:ProgramDataEqualLogicSAN HQAppletCache and retried launching the Group Manager. Credit goes out to Henrik Mikkelsen for suggesting to clear out any cache SAN HQ might have. I would like to use an Equallogic SAN as storage in SUSE Linux Enterprise Server 11.2. The EqualLogic Group was running firmware 5.2.2 and EqualLogic SAN HQ was running 2.1.100.5884 installed on Windows Server 2008 R2.
