IBM System Storage DS3500: Introduction and Implementation Guide
Out-of-band management offers the following advantages:
There is no need for an access logical drive (unlike for in-band management). Therefore,
you can use the maximum number of logical drives supported by the host servers’
operating system.
If the I/O paths fail, you can still access the DS3500 storage subsystem out-of-band, check
the status, and capture logs for effective troubleshooting. Access to both controllers is
required for almost all in-band management functions.
If in-band management cannot be used (for example, when the SMagent is not available
for the host server operating system), you can effectively use out-of-band management.
We recommend setting up and using both methods, if at all possible. This will introduce some
redundancy to your management setup and provide management access to the DS3500
subsystem even in the case of I/O path or Ethernet management network failure.
The IIBM System Storage DS Storage Manager package consists of the following
components:
Storage Manager Client (SMclient/SMcli)
Storage Manager Agent (SMagent)
Storage Manager Utility (SMutil)
Storage Manager multipath support
Java™ access bridge (for Windows only)
Storage Manager Client (SMclient)
This is the actual graphical user interface (GUI) that you use to manage the DS3500
subsystems. You install SMclient on the management station. This is usually not one of the
host servers, but rather a workstation that belongs to a system administrator. However, it is
also possible to install SMclient on a host server. There are two high level management
screens that are used for these functions:
Enterprise Management Window
Subsystem Management Window
Enterprise Management Window
This window opens when the DS3500 Storage Manager is launched. It lists the storage
subsystems it knows about. You can add new storage subsystems and perform various tasks
on the enterprise level. Below we show a sample of the Linux based Enterprise Management
Window in Figure 2-14.
