Hi,

We are also facing the issue while taking the backup o SAN drive.

The backup is completing fine on Non SAN storage but its failing on SAN by Giving error as I/O Failure Error: 1117.

When we try to backup it via SQL like 'BACKUP DATABASE....' its throwing the error as Semphore Timed Out.

Although some other backups are completing fine for same SQL Server on same SAN disk.

I am not able to figure it out if its and database issue or its hadware issue.

Could any one please help on this.

Regards,

GJ
