SpectrumSCM 3.0 (Default branch)
06-26-2008
SpectrumSCM is the first platform-independent,truly integrated enterprise-level SourceConfiguration and Management solution, whichincludes version control, process management,release management, advanced branching, issuetracking and much more, all integrated into onetool. In addition, it allows users to constructautomated workflow engines and interfaces toexternal systems through the SpectrumSCM API. Thetool also incorporates advanced security featuresthrough the Java Security Model, SSL, and LDAP.The client software can be run as an applicationor accessed over the Web as an applet or throughJava Web Start. It also includes a full-featuredcommandline interface, strong IDE integrations,and a SpectrumSCM Proxy for remote users. License: Other/Proprietary License with Free TrialChanges:|

ifc_disable_mgmt_lun(5) File Formats Manual ifc_disable_mgmt_lun(5) NAME
ifc_disable_mgmt_lun - select whether or not management luns are discovered in the legacy representation of mass storage devices VALUES
Failsafe Default Allowed values Enable discovery of management luns for array devices. Disable discovery of management luns for array devices. Recommended values DESCRIPTION
Management luns provide the means to access the control ports of Fibre Channel disk arrays. They are represented in both the legacy and the agile view of storage devices. The legacy representation of a management lun is typically created under a separate virtual extension bus node. The entry for a legacy management lun looks like this: On a system with a large number of storage devices connected, creation of management luns can result in an insufficient number of virtual extension buses for the legacy representation of data luns. Since the number of extension buses on a system is limited to 256, luns requiring virtual extension buses above 256 will be unusable through legacy device special files. Disabling the discovery and creation of management luns will free up virtual extension buses for use by data luns. Who Is Expected to Change This Tunable? System administrators who expect to use a large number of storage devices requiring more than 256 extension buses through legacy device special files. Restrictions on Changing Changes to this tunable take effect immediately. However, existing management luns will not be removed. When Should the Tunable Be Turned On? This tunable should be turned on when the system runs out of extension buses for configuring the legacy representation of data luns. What Are the Side Effects of Turning the Tunable Off? None. When Should the Tunable Be Turned Off? When the functionality provided by the management luns is desired. What Are the Side Effects of Turning the Tunable On? Existing management luns in the legacy representation will show up in the state. What Other Tunables Should Be Changed at the Same Time? None. WARNINGS
All HP-UX kernel tunable parameters are release specific. This parameter may be removed or have its meaning changed in future releases of HP-UX. Installation of optional kernel software, from HP or other vendors, may cause changes to tunable parameter values. After installation, some tunable parameters may no longer be at the default or recommended values. For information about the effects of installation on tun- able values, consult the documentation for the kernel software being installed.
