Smart Crash Handling
Hi,

Is there anything you can do to a *nix (SuSE Linux actually) which allows it to *try* to do a reboot if something crashes the system?

I know they have something at work (but I don't work with the servers myself) which makes the server reboot if it crashes/locks (works about 80% of the time). It means you don't have to power off manually and reboot in the event of a system crash - I'm just not sure how it's implemented.

Obviously it wont work for all types of crash.

My server currently seems to be in a state where it's returning Pings at about 120ms and none dropped but I can't SSH, Open web pages, FTP or anything else. It was freezing every so often last night and seems to have completely gone now that I'm not near it Smilie

Thanks for any help offered,

(Sitting here 40 miles from the server I wish this was in place on while I wait, knowing it's gonna be another 6 hours before I get to check what happened to it Smilie)

ciss

CISS(4) 						   BSD Kernel Interfaces Manual 						   CISS(4)

NAME

     ciss -- HP/Compaq Smart ARRAY 5/6 RAID controllers

SYNOPSIS

     ciss* at pci? function ?

DESCRIPTION

     The ciss driver provides support for the CISS interface implemented by fifth and later generations of the HP/Compaq Smart ARRAY family of
     controllers.

     The CISS interface is defined in the document entitled CISS Command Interface for SCSI-3 Support Open Specification, Version 1.04, Valence
     Number 1, Compaq Computer Corporation, 2000/11/27.

     This driver supports several Compaq and HP controllers implementing the CISS interface, including:

     o	 Compaq Smart Array 5300 version 1
     o	 Compaq Smart Array 5300 version 2
     o	 Compaq Smart Array 5i version 1
     o	 Compaq Smart Array 5i version 2
     o	 HP Smart Array 5312
     o	 HP Smart Array 6i
     o	 HP Smart Array 641
     o	 HP Smart Array 642
     o	 HP Smart Array 6400
     o	 HP Smart Array 6400 EM
     o	 HP Smart Array E200
     o	 HP Smart Array E200i
     o	 HP Smart Array P400
     o	 HP Smart Array P400i
     o	 HP Smart Array P600
     o	 HP Smart Array P800
     o	 HP Smart Array V100
     o	 HP Smart Array 1 through 13

     These controllers support RAID 0, RAID 1, RAID 5, JBOD, and superpositions of those configurations.

     Although the controllers are actual RAID controllers, the ciss driver makes them look just like SCSI controllers.	All RAID configuration
     must be done through the controllers' BIOSes.

     Hardware from previous generations of this product family may be supported by the cac(4) driver.
