Operating Systems Linux How to Find out if an HP/Linux uses SAN or not? Post 302762197 by tokiwinter on Monday 28th of January 2013 08:21:57 AM

Depends on the type of SAN, FC cards, whether multipathd is being used, etc.

You can try a few things. Run lspci and check for HBAs. Check dmesg. Specific things - check for kernel modules loaded for your HBA, check your multipathd config, etc. Some specific HBAs/fabric setups have their own drivers/software (PowerPath for EMC, SanSurfer for QLogic). Check with your storage admins.

Thoughts/experiences of SAN attaching V880 to EMC SAN

Hi everyone, I wonder if I can canvas any opinions or thoughts (good or bad) on SAN attaching a SUN V880/490 to an EMC Clarion SAN? At the moment the 880 is using 12 internal FC-AL disks as a db server and seems to be doing a pretty good job. It is not I/O, CPU or Memory constrained and the... (2 Replies)

NAME
mkqdisk - Cluster Quorum Disk Utility WARNING
Use of this command can cause the cluster to malfunction. SYNOPSIS
mkqdisk [-?|-h] | [-L] | [-f label] [-c device -l label] [-d [-d ...]] DESCRIPTION
The mkqdisk command is used to create a new quorum disk or display existing quorum disks accessible from a given cluster node. OPTIONS
-c device -l label Initialize a new cluster quorum disk. This will destroy all data on the given device. If a cluster is currently using that device as a quorum disk, the entire cluster will malfunction. Do not run this on an active cluster when qdiskd is running. Only one device on the SAN should ever have the given label; using multiple different devices is currently not supported (it is expected a RAID array is used for quorum disk redundancy). The label can be any textual string up to 127 characters - and is therefore enough space to hold a UUID created with uuidgen(1). -f label Find the cluster quorum disk with the given label and display information about it. -L Display information on all accessible cluster quorum disks. -d Increase debugging level. Specify multiple times for more information. Currently, specifying more than twice has no effect. SEE ALSO
