HANA DB Backup failing with Error

Hi All,

We are facing issues while taking backup of HANA DB, it fails with below error:

Index server backup fails with below error:

backup could not be completed, Error during asynchronous file transfer, rc=5: Input/output error; $fileCallback$=[R] , buffer= 0x00007f7ebb6ab000, offset= 39959134208, size= 0/4194304, file= "<root>/datavolume_0000.dat" ((open, mode= RW, access= rw-rw-r--, flags= DIRECT|MUST_EXIST), factory= (root= "/hana/data/SID/mnt00001/hdb00002/" (access= rw-rw-r--, flags= AUTOCREATE_DIRECTORY, usage= DATA, fs= xfs, config= (async_write_submit_active=auto,async_write_submit_blocks=all,async_read_submit=on,num_submit_queues=1,num_completion_queues=1,size_kernel_io_queue=512,max_parallel_io_requests=64,min_submit_batch_size=16,max_submit_batch_size=64))) {shortRetries= 0, fullRetries= 10 (10/10)}

We have checked SAP note 2062631 where such situation is faced while accessing file system in HA env with SP8

Can anyone help me.

Thanks,

Sharib

    Hi

    The input/output error can also happen if a file in persistence is no longer accessible for a service because a SAP HANA failover mechanism has moved it away from the host. See SAP Note 2062631 that describes ping-pong failover situations that can be responsible.

    Check in collaboration with your hardware and OS partners why the mentioned file can't be accessed sporadically or permanently.

    Hi,

    As mentioned in the note get the original node network to be shutdown first , get networks to resolve the issue then bring everything back up.

    What actions have you taken thus far?

    Kind Regards,
