Host storage sensor

The host storage sensor discovers the storage that is attached to a host computer system, including storage area network (SAN) storage. This sensor extends the storage discovery that is provided by the storage sensor.

The host storage and storage sensors discover the same storage resources, for example, disks, partitions, logical volumes, physical volumes, and file systems. The host storage sensor also discovers the following storage resources:

  • Fibre Channel (FC) volumes
  • FC ports
  • Host bus adapters

Prerequisites

For 64-bit Linux targets
Fix Pack 6

The 32-bit glibc library is required, only when 32-bit version of collectionEngine binary is used by the sensor (Default).

Fix Pack 9If collectionEngineBuild_64_Bit option is set to true, then 32-bit glibc is not required but 64-bit glibc is required.

Limitations

When you discover storage attached to a target computer using the storage sensor, do not carry out a discovery on the same system using this sensor.

Fix Pack 6You must install Vendor's host bus adapter (HBA) API library files (32-bits). Fix Pack 9Instead of 32 bit, vendor's 64-bit HBA API library files are required when sensor uses 64-bit collection engine binary.

The sensor does not discover the ZFS file systems on the Solaris target systems.

Do not run the sensor on AIX LPARs, where the LPAR's configuration is attached to the BR8470 FCoE switch that runs FOS v6.4.3_dcb in Access Gateway mode. It leads to an unexpected behavior of systems that are connected to that FC Switch. Use FOS7.0.2e, or later.

Security issues

By default, root user privileges are required to discover SAN resources in UNIX environments. Typically, this escalation is done by setting the file access permissions using the setuid (set-user-ID mode bit) term or by using the sudo command.
