Definition of UNIX target
Unix targets are defined by the operating system group that comprises:
- Solaris
- AIX
- HP-UX
These O/S can be scanned by the CAM product but restrictions do apply of which a customer should be aware. This document attempts to identify these restrictions and associated best practices familiar to the customer. A summary of the coverage of all O/S is available on the Scanning Support Matrix.
Metrics
The following operating systems do not support the generation of O/S metrics. Metrics in this case would typically include, network traffic, CPU load, etc. taken over an extended period of time (typically 2 weeks). The collection of metrics is used by the product to identify the migration of targets to cloud equivalents by establishing the right-sizing of the targets cloud environments. Right-sizing is the practice of ensuring that the cloud target environment has appropriate CPU, network, and disk resources to properly accommodate the migration.

Scanning
The following information relates to scanning operations across Unix-based environments
Unique Identifier Scanning
Scanning of UNIX targets is typically based on O/S commands to generate a unique ID using commands that are “native” to O/S. Within the LINUX and Windows domains, the tools used tend to be ubiquitous across these domains. However, within UNIX, a standard set of commands is more differentiated and may or may not be present depending on O/S configuration options that have been supplied.

Solaris |
8.x → 11.4 |
Uses commands Requires admin privilege escalation SUDO for inventory/scanning for credentials used for scanning. The sudo utility is considered as part of the Oracle Solaris 10 1/13 release but due to technical reasons sudo packages were released independently and they are not within Oracle Solaris 10 1/13 media |

AIX |
5.x, 6.x, 7.x |
Uses commands Requires availability of lsof or netstat and admin privilege escalation SUDO for inventory/scanning for credentials used for scanning |

HP-UX |
10x, 11x |
Uses commands Requires availability of lsof or netstat and admin privilege escalation SUDO for inventory/scanning for credentials used for scanning |
For these operating systems, is not unusual for some or all of these commands not to return enough information to allow CAM to uniquely identify a target server. The CAM scan of such a target will be marked with a warning stating that specific commands could not be used/did not generate enough information.
In the case that a server could not use native commands to generate a unique identifier,
CAM provides the functionality to generate a unique identifier.
This unique identifier is written to the target and is retained for future scan operations.
The unique identifier is stored in the file:/var/tmp/CloudSphere/uuid/uniqueIdentifier.txt
All targets that cannot generate their own identifier should be moved to a separate scan job (and either remove or exclude them from the original scan job).
Remediation Process for Unique Identifier
- Create a new scan job.
- Select the details tab.
- Under the “Enablings” field, add the option
EnableGeneratedID. - Once the servers within this job's scope have been scanned, they will be discovered using a CAM-generated identifier.
Disk Scanning
Within a Solaris zones virtualized environment, the VMs that reside in the non-global zone do not have access to global disk information. This will cause a ‘partial scan’ status to be identified when scanning these server types. This is an expected scenario for these servers.
