z/OS discovery
Discovery and Service Mapping Patterns finds computers running the z/OS operating system using the IBM zOS Server pattern. Discovering some of these resources may require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.

The IBM zOS Server pattern performs infrastructure-level discovery for z/OS servers. To discover applications on z/OS, use application patterns, such as DB2 on Linux, WMQ On Unix, or Websphere On Unix. For more information, see IBM z/OS Discovery requirements and expectations [KB0623031] article in the Now Support Knowledge Base.
Prerequisites
Verify that the UNIX System Services (USS) is running on port 22
Verify that the USS service is running on port 22 on z/OS.
Verify the required commands on the host machine
Verify that you can run the following commands on the host machine:
unamehostnamesysvar SYSNAMEnetstatdflscatgreppscut- Verify required permissions
Verify that you have the following permissions:
- Write permission to
/tmp - Read access to all user processes
- Ability to run REXX scripts
- Create SSH credentials
For more information, see SSH credentials.
Data collected by Discovery during horizontal discovery
Discovery populates the data in the CMDB when running the IBM zOS Server pattern. The pattern discovers USS-mounted file systems.
| Field | Description |
|---|---|
| Name \[name\] | Hostname of the z/OS system. |
| OS Version \[os\_version\] | z/OS operating system version. For example: V2R5 or 3.1. |
| Operating System \[os\] | Operating system type. The value is set to IBM_ZOS. |
| Manufacturer \[manufacturer\] | Hardware manufacturer. The value is set to IBM. |
| Serial number \[serial\_number\] | Hardware chassis serial number. |
| Model ID \[model\_id\] | Hardware model display name based on model code lookup. For example: z14, z15, or zEnterprise 196.If the model code isn’t in the lookup table, this field remains empty. |
| IP Address \[ip\_address\] | Management IP address used for discovery connection. |
| Field | Description |
|---|---|
| IP Address [ip_address] | IPv4 or IPv6 address. |
| Netmask [netmask] | Network mask for the IP address. The value is set to 0.0.0.0. |
| MAC Address [mac_address] | Hardware MAC address. If unavailable, the value is set to NOT_FOUND. |
| Nic [nic] | References the Network Adapter [cmdb_ci_network_adapter] table. |
| Field | Description |
|---|---|
| Name [name] | Network interface name. If unavailable, the value is set to VIP. |
| IP Address [ip_address] | IPv4 or IPv6 address assigned to this network adapter. |
| Netmask [netmask] | Network mask for the adapter. The value is set to 0.0.0.0. |
| MAC Address [mac_address] | Hardware MAC address for the network adapter. If unavailable, the value is set to NOT_FOUND. |
| Configuration Item [cmdb_ci] | References the IBM zOS server [cmdb_ci_ibm_zos_server] table. |
| Field | Description |
|---|---|
| Name [name] | Name of the USS file system set to the mount point path. For example: /, /tmp, or /u. |
| Volume ID [volume_id] | Volume identifier, set to the mount point path. |
| Mount point [mount_point] | Directory path where the file system is mounted in the USS hierarchy. |
| File system [file_system] | USS dataset name of the zFS file system. For example: OMVS.ROOT.ZFS or OMVS.TMP.ZFS. |
| Size bytes [size_bytes] | Total capacity of the file system in kilobytes (KB), as retrieved by the df -Pkv command. |
| Free space bytes [free_space_bytes] | Available free space in the file system in KB, as retrieved by the df -Pkv command. |
| Computer [computer] | References the IBM zOS server [cmdb_ci_ibm_zos_server] table. |
