I have a silicon image 3124 based pci card that is port multiplier compatible (it works fine under win xp) that is only showing one of 5 attached drives when attached to a Redhat 5 computer, with both 2.6.18-8.1.15.el5 and 2.6.23.1. The SATA link shows as up for the one recognized drive, the other four drives show the link down.Any sugguestions as to what may be the problem? I'm using the sata_sil24 driver.
A subset of what I consider the relavant portion of dmesg for the 2.6.18-8.1.15.el5 kernel is: ahci 0000:00:1f.2: AHCI 0001.0200 32 slots 6 ports 3 Gbps 0x2f impl SATA mode ahci 0000:00:1f.2: flags: 64bit ncq pm led clo pmp pio slum part ata1: SATA max UDMA/133 cmd 0xF882C100 ctl 0x0 bmdma 0x0 irq 233 ata2: SATA max UDMA/133 cmd 0xF882C180 ctl 0x0 bmdma 0x0 irq 233 ata3: SATA max UDMA/133 cmd 0xF882C200 ctl 0x0 bmdma 0x0 irq 233 ata4: SATA max UDMA/133 cmd 0xF882C280 ctl 0x0 bmdma 0x0 irq 233 ata5: SATA max UDMA/133 cmd 0xF882C300 ctl 0x0 bmdma 0x0 irq 233 ata6: SATA max UDMA/133 cmd 0xF882C380 ctl 0x0 bmdma 0x0 irq 233 scsi0 : ahci ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300) ata1.00: ATA-7, max UDMA/133, 488281250 sectors: LBA48 NCQ (depth 31/32) ata1.00: ata1: dev 0 multi count 0 ata1.00: configured for UDMA/133 scsi1 : ahci ata2: SATA link up 3.0 Gbps (SStatus 123 SControl 300) ata2.00: ATA-7, max UDMA/133, 488281250 sectors: LBA48 NCQ (depth 31/32) ata2.00: ata2: dev 0 multi count 0 ata2.00: configured for UDMA/133 scsi2 : ahci ata3: SATA link up 1.5 Gbps (SStatus 113 SControl 300) ata3.00: ATAPI, max UDMA/100 ata3.00: configured for UDMA/100 scsi3 : ahci ata4: SATA link down (SStatus 4 SControl 300) scsi4 : ahci ata5: SATA link down (SStatus 0 SControl 0) scsi5 : ahci ata6: SATA link down (SStatus 4 SControl 300) Vendor: ATA Model: Hitachi HDT72502 Rev: V5DO Type: Direct-Access ANSI SCSI revision: 05 SCSI device sda: 488281250 512-byte hdwr sectors (250000 MB) sda: Write Protect is off sda: Mode Sense: 00 3a 00 00 SCSI device sda: drive cache: write back SCSI device sda: 488281250 512-byte hdwr sectors (250000 MB) sda: Write Protect is off sda: Mode Sense: 00 3a 00 00 SCSI device sda: drive cache: write back sda: sda1 sd 0:0:0:0: Attached scsi disk sda Vendor: ATA Model: Hitachi HDT72502 Rev: V5DO Type: Direct-Access ANSI SCSI revision: 05 SCSI device sdb: 488281250 512-byte hdwr sectors (250000 MB) sdb: Write Protect is off sdb: Mode Sense: 00 3a 00 00 SCSI device sdb: drive cache: write back SCSI device sdb: 488281250 512-byte hdwr sectors (250000 MB) sdb: Write Protect is off sdb: Mode Sense: 00 3a 00 00 SCSI device sdb: drive cache: write back sdb: sdb1 sd 1:0:0:0: Attached scsi disk sdb Vendor: PBDS Model: DVD+-RW DH-16W1S Rev: 2D14 Type: CD-ROM ANSI SCSI revision: 05 sata_sil24 0000:03:02.0: version 0.3 ACPI: PCI Interrupt 0000:03:02.0[A] -> GSI 18 (level, low) -> IRQ 217 ata7: SATA max UDMA/100 cmd 0xF8840000 ctl 0x0 bmdma 0x0 irq 217 ata8: SATA max UDMA/100 cmd 0xF8842000 ctl 0x0 bmdma 0x0 irq 217 ata9: SATA max UDMA/100 cmd 0xF8844000 ctl 0x0 bmdma 0x0 irq 217 ata10: SATA max UDMA/100 cmd 0xF8846000 ctl 0x0 bmdma 0x0 irq 217 scsi6 : sata_sil24 ata7: SATA link down (SStatus 0 SControl 300) scsi7 : sata_sil24 ata8: SATA link down (SStatus 0 SControl 300) scsi8 : sata_sil24 ata9: SATA link up 3.0 Gbps (SStatus 123 SControl 300) ata9.00: ATA-7, max UDMA/133, 1953525168 sectors: LBA48 NCQ (depth 31/32) ata9.00: ata9: dev 0 multi count 16 ata9.00: configured for UDMA/100 scsi9 : sata_sil24 ata10: SATA link down (SStatus 0 SControl 300) Vendor: ATA Model: Hitachi HDS72101 Rev: GKAO Type: Direct-Access ANSI SCSI revision: 05 SCSI device sdc: 1953525168 512-byte hdwr sectors (1000205 MB) sdc: Write Protect is off sdc: Mode Sense: 00 3a 00 00 SCSI device sdc: drive cache: write back SCSI device sdc: 1953525168 512-byte hdwr sectors (1000205 MB) sdc: Write Protect is off sdc: Mode Sense: 00 3a 00 00 SCSI device sdc: drive cache: write back sdc: sdc1 sd 8:0:0:0: Attached scsi disk sdc [EMAIL PROTECTED] ~]# fdisk -l Disk /dev/sda: 250.0 GB, 250000000000 bytes 255 heads, 63 sectors/track, 30394 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 30394 244139773+ 83 Linux Disk /dev/sdb: 250.0 GB, 250000000000 bytes 255 heads, 63 sectors/track, 30394 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sdb1 1 30394 244139773+ 83 Linux WARNING: GPT (GUID Partition Table) detected on '/dev/sdc'!
