NAME¶

SAPHanaSR-showAttr - Shows Linux cluster attributes for SAP HANA system replication.

SYNOPSYS¶

SAPHanaSR-showAttr [ --help | --version ]
SAPHanaSR-showAttr [ --sid=SID ] [ --ino=INO ] [ --sort=KEY ]

DESCRIPTION¶

SAPHanaSR-showAttr shows Linux cluster attributes for SAP HANA system replication automation. The overall system replication (SR) state is shown as well as the HANA state on each node. If the HANA srHook method srConnectionChanged() is configured, the respective information is shown as well.

The output shows three sections:

Global section

global (Global)
primary replication site (prim)
secondary replication site (sec)
replication state of secondary site, indicated by systemReplicationStatus.py (sec_sync_state)
replication channel state indicated by srConnectionChanged (srHook)

Site section

site name (Site)
last primary timestamp (lpt)
landscape synchronisation status (lss)
current master nameserver for that site (mns)
system replication role (srr)

Hosts section

hostname (Hosts)
state of the Linux cluster resource (clone_state)
actual and configured roles for HANA on that node (roles)
actual master score on that node (score)
site where the host sits (site)

OPTIONS¶

--help
show help.

--version
show version.

--ino NUM
use SAP instance number NUM. Should be autodetected, if there is only one SAP HANA instance installed on the local cluster node. The SAP instance number must be represented by a two digit numer like 00, 05 or 42. Some numbers ares not allowed, f.e. 98.

--sid SID
use SAP system ID SID. Should be autodetected, if there is only one SAP HANA instance installed on the local cluster node. The SAP system ID is a 3 alphanum string with a valid SAP system name like SLE, HAE, FH1, C11, or P42.

--sort FIELD
sort Hosts section table by field. Allowed values: roles, site. The default sort is by hostnames.

RETURN CODES¶

0 Successful program execution.
>0 Usage, syntax or execution errors.

EXAMPLES¶

# SAPHanaSR-showAttr --sort roles

show all SAPHanaSR attributes in the cluster and sort host table output by roles

FILES¶

/usr/bin/SAPHanaSR-showAttr

the program itself.

/usr/sap/hostctrl/exe/saphostctrl
