# Seagate drives (Barracuda 7200.11, DiamondMax 22, Barracuda ES.2 SATA, SV35) fail after powering on, KB 207931:
# http://seagate.custkb.com/seagate/crm/selfservice/search.jsp?Tab=search&Module=selfservice&TargetLanguage=selfservice&DocId=207931&NewLang=en
#
# There is no Linux tool (yet) to help the overworked linux admin,
# so I wrote this - have fun mass-checking your servers.
#
# Currently supports hdparm, tw_cli (3ware), arcconf (adaptec)
# You have to use the corresponding RAID-Tool in order to get the model, serial and firmware version.
#
# Hint: 
# do something like this:
# ssh host "curl -s https://deploysrv/seagate-207931.sh | sh"
#
# The script has return codes:
# 0: everything ok
# 1: one of the models was found (you still need to check the firmware version)
#
# If you have code additions, mail me, I'd like to add support for more cli raid-tools.
# Please supply me with complete output - or just buy me an areca, lsi and I'll add support for those, too ;)
