I am trying to determine the best way to patch a pile of Redhat 6.2 (zoot)systems to recognize 1Terabyte and larger disks. I am trying to directly attach 1.5Terabyte (external) RAID arrays to these Redhat 6.2 systems via Ultra160 SCSI adapters. The RAID devices are external rackmount enclosures with their own hardware IDE->Ultra160 SCSI RAID Controller. They use 160 Gigabyte IDE drives internally in a RAID5 configuration w/ no hot spare. The units striped in this configuration present the host they are directly attached to with about 1.5 Terabytes of storage as (1) Logical disk. Neither Redhat 6.2 or 7.2 will see properly recognize this large of a disk. The dmesg see's the RAID on the SCSI chain, assigns it 'sdb' but claims it has a negative number of sectors, and im unable to fdisk the device. The cut-off point for large disks in Redhat 6.2 and 7.2 appears to be around 900 Gigabytes, I can get both Redhat 6.2 and 7.2 to see up to around 900 gigs as 1 disk. I've heard about a 64-bit IO patch for an older 2.x.x 'pre8' release kernel but would like to know if theres a way to get this accomplished with Redhat 6.2/Kernel 2.2.14-5. Any insight into this problem would be greatly appreciated! Thanks! -Bobd _________________________________________________________________ Send and receive Hotmail on your mobile device: http://mobile.msn.com
