Mark, I've not done it on 390, but it is possible. You'll need raid compiled IN the kernel (not a module - unless you load it from a initrd disk), and you need to change your partition type to "Raid Autodetect". On Intel its partition type 8e, but I dont know how you do that on minidisk partitions. Does fdasd let you change the partition type?
Anyway, wouldnt it be better to have the raid done at the hardware/DASD layer, and not burn CPU cycles keeping raided minidisks in sync? ...deon --- Have you looked at the A/NZ Tivoli User Group website? http://www.tuganz.org Deon George, Customer Support Account Engineer, IBM Australia Office: +61 3 9626 6058, Fax: +61 3 9626 6622, Mobile: +61 412 366 816, IVPN +70 66058 mailto:[EMAIL PROTECTED], http://www.ibm.com/tivoli Mark D Pace <[EMAIL PROTECTED]> Sent by: Linux on 390 Port <[EMAIL PROTECTED]> 01/07/2003 06:57 AM Please respond to Linux on 390 Port <[EMAIL PROTECTED]> To [EMAIL PROTECTED] cc Subject RAID and root FS Is it possible to run root '/' FS on a software raid?
