mount disk attached to HBA
Hello all,
I am building an cluster based on RedHat AS 3. I've installed Emulex LP8000 HBAs and have successfully compiled and activated the drivers. There is a good link light for each machine attached to the SAN fabric. My question is frustratingly simple. How do I mount the disk set aside for each node? I know how to mount disks but what would be the device name for the disk attached to the HBAs? /dev/sdaxx ??? or something else ? In Solaris I can just type "format" and it will list all the disk that the OS can "see" mounted or unmounted. Is there a similar command in Linux? Jack |
Ok, I've figured out how to mount the disk I was looking for. I used fdisk
fdisk /dev/sdb and fdisk /dev/sdc and I was able to see the disk on our SAN. I still have a question reguarding the format command is Solaris. Is there an equivalent command in Linux. Here is some output from a Solaris box. / -1> format Searching for disks...done AVAILABLE DISK SELECTIONS: 0. c0t0d20 <HP-OPEN-V-SUN-2104 cyl 59316 alt 2 hd 15 sec 128> /ssm@0,0/pci@1a,700000/fibre-channel@3/sd@0,14 1. c1t0d20 <HP-OPEN-V-SUN-2104 cyl 59316 alt 2 hd 15 sec 128> /ssm@0,0/pci@1e,700000/fibre-channel@3/sd@0,14 2. c2t0d0 <SUN18G cyl 7506 alt 2 hd 19 sec 248> /ssm@0,0/pci@1a,700000/pci@2/SUNW,isptwo@4/sd@0,0 3. c2t1d0 <SUN18G cyl 7506 alt 2 hd 19 sec 248> /ssm@0,0/pci@1a,700000/pci@2/SUNW,isptwo@4/sd@1,0 Specify disk (enter its number): It would be nice if I could do this in linux instead of guessing where a device might be. The closest thing I could find was the Disk Partitioning module in Webmin. Thanks Jack |
Hi Jack, Try
fdsk -l should give you everything connected. |
opps, I meant
fdisk -l |
