The backup servers are not able to see the Media Changer (the tape library) and so backup did not run last night. I tried to manage the PV136T through the web interface but it did not load properly. I downloaded the new firmware for the PV136T and upgraded the Remote Management Unit (RMU) which provides the web interface. Once I get the web interface to work, I upgraded the Library Modules and requested our hosting operator to reboot the tape library. However, it still doesn’t work. I restarted the servers but still no luck. After a few attempts, I give up and decided to go the hosting site.
Once I reached the hosting site, I removed all tapes, powered down the PV136T, reseated all the tape drives and powered down the two master backup servers. Then I powered up the PV136T and wait for it to finish initializing. Then I powered up the backup servers and it works. I tested out the backup and everything is back to normal.
At the same time, I discovered one of the servers has a faulty harddisk and had reported the case. Will be changing the harddisk tomorrow morning and hopefully the other harddisk will not fail tonight since it is RAID 1.
