Unable to connect HDB in sap hana

I'm trying to connect my HDB database using below command.

hdbsql -u SYSTEM -p password -d HDB -i 00

But, is throws below error even though I have HDB (tenant) database.

* 2: general error: database 'HDB' is unavailable SQLSTATE: HY000

Here is HDB info results.

hdbadm    3329  3242  6.0 6975692 3908564      \_ hdbnameserver
hdbadm    4538  3242  2.3 3125912 474896      \_ hdbcompileserver

hdbadm    7414  3242  2.2 3425392 642704      \_ hdbwebdispatcher

When I start database with HDB start command it's not showing any error message.

Please help me to find the root cause of this issue.

    Can you connect to the system database and run: select * from "SYS"."M_DATABASES" ? It should show the status of the tenant db.

    Also, you can use "alter system start database <<tenant db id>>" to start a tenant.
