awesome reply alivn
from my point of view ithnk so if not please correct ----any one can suggest me------
coz inthis sort of scenarios only u will have two options
1. as mentioned by alivn
2. think for the solutions sort-out in parallel consult ur senior dba and windows team also
[1.check the error logs in sqlserver and event-viewer
2. check the disk-space issues
3.what ever the high availability it is running on first check ur sqlserver services running or not --- if not restart the services which takes min 15mins downtime.
2. restore the full backup or point in time restore (tlogbackup .trns )]
sorry if any wrong ideas shared am not highly experienced iam starter in this domain
Thanks
