run_cmd run_cmd(cmd => 'command', [runas => 'user', timeout => 60]);

Runs a command C<cmd> via ssh in the given VM and log the output.
All commands are executed through C<sudo>.
If 'runas' defined, command will be executed as specified user,
otherwise it will be executed as root.

cmd - command string to be executed remotely

timeout - command execution timeout

title - used in record_info

runas - pre-pend the command with su to execute it as specific user

... - pass through all other arguments supported by run_ssh_command

get_promoted_hostname() get_promoted_hostname();

Checks and returns hostname of HANA promoted node according to crm shell output.

sles4sap_cleanup

Clean up Network peering and qesap deployment
This method does not internally die and try to execute
terraform destroy in any case.
Return 0 if no internal error.

cleanup_called - flag to indicate cleanup status

ansible_present - flag to indicate ansible has need executed as part of the deployment

get_hana_topology Parses command output, returns hash of hashes containing values for each host.

is_hana_online is_hana_online([timeout => 120, wait_for_start => 'false']);

Check if hana DB is online.

wait_for_start - Define 'wait_for_start' to wait for DB to start.

timeout - timeout for the wait of the online state

is_hana_resource_running is_hana_resource_running([quiet => 0]);

Checks if resource msl_SAPHanaCtl_* is running on given node.

quiet - if set, returns the value without recording info (default: 0)

is_hana_node_up is_hana_node_up($my_instance, [timeout => 900]);

Waits until 'is-system-running' returns successfully on the target instance.

instance - the instance the test needs to wait for

timeout - how much time to wait for before aborting

stop_hana stop_hana([timeout => $timeout, method => $method]);

Stops HANA database using default or specified method.
"stop" - stops database using "HDB stop" command.
"kill" - kills database processes using "HDB -kill" command.
"crash" - crashes entire OS using "/proc/sysrq-trigger" method.

method - Allow to specify a specific stop method

timeout - only used for stop and kill

start_hana start_hana([timeout => 60]);

Start HANA DB using "HDB start" command

cleanup_resource cleanup_resource([timeout => 60]);

Cleanup resource 'msl_SAPHanaCtl_*', wait for DB start automatically.

timeout - timeout for waiting resource to start

check_takeover check_takeover();

Checks takeover status and waits for finish until successful or reaches timeout.

enable_replication enable_replication([site_name => 'site_a', hana_inn => '10' ]);

Re-enables replication on the previously fenced database node. Database must be offline.
Dies if the the given <site name> doesn't correspond with the SAPHanaSR topology local site name
Optionaly the 'hana_innstance_id' could be provided for better reliability

site_name - local HANA site name of the site to be registered

hana_inn - optional HANA instance number to be registered

get_replication_info get_replication_info();

Parses "hdbnsutil -sr_state" command output.
Returns hash of found values converted to lowercase and replaces spaces to underscores.

get_promoted_instance get_promoted_instance();

Retrieves hostname from currently promoted (Master) database and returns instance data from $self->{instances}.

wait_for_sync wait_for_sync([timeout => $timeout]);

Wait for replica site to sync data with primary.
Checks "SAPHanaSR-showAttr" output and ensures replica site has "sync_state" "SOK && PRIM" and no SFAIL.
 Continue after expected output matched N times continually to make sure cluster is synced.

Expected conditions:
 - Both primary and replica must be online.
 - primary must have sync_state 'PRIM'
 - primary must have clone_state 'PROMOTED'
 - replica must have sync_state 'SOK'  - this means data is in sync
 - replica must have clone_state 'DEMOTED'
 - site order does not matter

timeout - timeout for waiting sync state

wait_for_pacemaker wait_for_pacemaker([timeout => $timeout]);

timeout - timeout for waiting for pacemaker service

change_sbd_service_timeout $self->change_sbd_service_timeout(service_timeout => '30');

Overrides timeout for sbd systemd service to a value provided by argument.
This is done by creating or changing file "/etc/systemd/system/sbd.service.d/sbd_delay_start.conf"

service_timeout - value for the TimeoutSec setting

setup_sbd_delay_publiccloud $self->setup_sbd_delay_publiccloud();

Set (activate or deactivate) SBD_DELAY_START setting in /etc/sysconfig/sbd.
Delay is used in case of cluster VM joining cluster too quickly after fencing operation.
For more information check sbd man page.

Setting is changed via OpenQA parameter: HA_SBD_START_DELAY
Possible values:
"no" - do not set and turn off SBD delay time
"yes" - sets default SBD value which is calculated from a formula
"<number of seconds>" - sets specific delay in seconds

Returns integer representing wait time.

sbd_delay_formula $self->sbd_delay_formula();

return calculated sbd delay

cloud_file_content_replace cloud_file_content_replace(filename => $filename, search_pattern => $search_pattern, replace_with => $replace_with);

filename - file location

search_pattern - search pattern

replace_with - string to replace

create_instance_data

Create and populate a list of publiccloud::instance and publiccloud::provider compatible
class instances.

provider - Instance of PC object "provider", the one usually created by provider_factory()

deployment_name

Return a string to be used as value for the deployment_name variable
in the qe-sap-deployment.

get_hana_site_names

Get primary and secondary site name.
This information is both needed to configure the qe-sap-deployment
and later in the test when calling `hdbnsutil -sr_register`.
This function mostly read the information from job settings
HANA_PRIMARY_SITE and HANA_SECONDARY_SITE, so main reason to have
it behind a function is to have coherent defaults.

create_hana_vars_section

max_retries - maximum number of retries, default 7

wait_for_zypper

The function attempts to run 'zypper ref' to check for a lock. If Zypper is locked, it waits for a specified delay before retrying.
Returns normally if Zypper is not locked or dies after a maximum number of retries if Zypper remains locked.

$instance - The instance object on which the Zypper command is executed. This object must have the run_ssh_command method implemented.

time fatal) after displaying cluster information.

$timeout - The timeout (in seconds) for the command.
