I am using this card to connect to my external storage array. During system startup, the Card BIOS has no problem detecting the card and the external storage devices. However when I boot into the OS, and do a fdisk -l, my external storage devices cannot be detected. I tried the following to verifying that sym53c8xx is properly loaded: </tt>[root@rh114 2.6.9-5.ELsmp-i686]# modprobe sym53c8xx [root@rh114 2.6.9-5.ELsmp-i686]# lsmod Module Size Used by nbd 26593 0 raid1 19905 0 autofs4 23237 0 i2c_dev 11329 0 i2c_core 22081 1 i2c_dev sunrpc 157093 1 dm_mod 54741 0 button 6481 0 battery 8901 0 ac 4805 0 md5 4033 1 ipv6 232705 18 uhci_hcd 31065 0 hw_random 5845 0 e100 39493 0 mii 4673 1 e100 e1000 79693 0 floppy 58481 0 sg 33377 0 ext3 116809 4 jbd 71257 1 ext3 aic79xx 190589 5 sym53c8xx 69857 0 scsi_transport_spi 13761 1 sym53c8xx sd_mod 17217 6 scsi_mod 121421 5 sg,aic79xx,sym53c8xx,scsi_transport_spi,sd_mod <tt>It seems that the driver module is loaded by the OS, but why am I not seeing my external disks? Can someone advise on this? Thanks.</tt> </body> Disclaimer Clause : The information in this e-mail (including attachments) is confidential and is only intended for use by the addressee.
