om vol print base devs

Print the list of base devices the local service instance or the specified resources are layered on.

–color=<string>

Colorize output. Possible values are:

• auto: guess based on tty presence

• always|yes: always colorize

• never|no: never colorize

–daemon

A flag inhibiting the command daemonization. Set by the daemonization routine.

–debug

Increase stream and file log verbosity up to the debug level.

–env

Export the uppercased variable in the os environment.

With the create action only, set a env section parameter in the service configuration file. Multiple --env <key>=<val> can be specified. For all other actions.

–filter=<string>

A JSONPath expression to filter a JSON output.

–format=<string>

Specify a data formatter. Possible values are json, flat_json, csv or table. csv and table formatters are available only for commands returning tabular data.

–local

Execute the service action on the local service instances only, ignoring cluster-wide considerations.

–namespace=<string>

The namespace to switch to for the action. Namespaces are cluster partitions. A default namespace can be set for the session setting the OSVC_NAMESPACE environment variable.

–node=<string>

The node to send a request to. If not specified the local node is targeted.

–rid=<string>

A resource specifier expression like <spec>[,<spec>], where <spec> can be:

• A resource id

• A driver group name (app, fs, disk, …)

Examples:

• app all app resources

• container#1,ip#1 only container#1 and ip#1

–status=<string>

Operate only on service with a local instance in the specified availability status (up, down, warn, …).

–subsets=<string>

Limit the action to the resources in the specified, comma-separated, list of subsets.

–tags=<string>

A comma-separated list of resource tags to limit action to. The + separator can be used to impose multiple tag conditions. For example, tag1+tag2,tag3 limits the action to resources with both tag1 and tag2, or tag3.

–waitlock=<string>

A duration expression like 5s. The maximum wait time when acquiring the service action lock.

-h, –help

Show this help message and exit.

-p, –parallel

Start actions on specified services in parallel. max_parallel in node.conf limits the number of parallel running subprocesses.

-s, VAL, –service=<string>

A service selector expression [!]<expr>[<sep>[!]<expr>] where:

• ! is the expression negation operator

• <sep> can be:

  • , OR expressions

  • + AND expressions

• <expr> can be:

  • a shell glob on service names

  • <param><op><value> where:

    • <param> can be:

      • <rid>:

      • <group>:

      • <rid>.<key>

      • <group>.<key>

      • <single value jsonpath expression on the $.monitor.services.<path> dictionary extended under the 'nodes' key by each instance 'status' and 'config' data>

    • <op> can be:

      • < > <= >= =

      • ~ the string or any list element matches the regexp value

      • ~= the string matches regexp value or any list element is the value

Examples:

• *dns,ha*+app.timeout>1

• ip:+task:

• !*excluded

• $.avail=warn

• $.nodes.*.status.avail=warn

Note:

• ! usage requires single quoting the expression to prevent shell history expansion
