I am currently using an old server with an old storage connected by fiberchannel. On the storage side I left everything configured but on the server side I do not see the disk that was created for it. Here is what I have so far:
[root@vmprod01 ~]# lspci | grep Fibre 10:00.0 Fibre Channel: Emulex Corporation Zephyr-X LightPulse Fibre Channel Host Adapter (rev 02) 10:00.1 Fibre Channel: Emulex Corporation Zephyr-X LightPulse Fibre Channel Host Adapter (rev 02)
[root@vmprod01 ~]# lspci -v -s 10:00.0 10:00.0 Fibre Channel: Emulex Corporation Zephyr-X LightPulse Fibre Channel Host Adapter (rev 02) Subsystem: Emulex Corporation Zephyr-X LightPulse Fibre Channel Host Adapter Physical Slot: 2 Flags: bus master, fast devsel, latency 0, IRQ 26 Memory at c7eff000 (64-bit, non-prefetchable) [size=4K] Memory at c7efec00 (64-bit, non-prefetchable) [size=256] I/O ports at 6000 [size=256] [virtual] Expansion ROM at c6000000 [disabled] [size=256K] Capabilities:  Power Management version 2 Capabilities:  MSI: Enable+ Count=1/16 Maskable- 64bit+ Capabilities:  Express Endpoint, MSI 00 Capabilities:  Advanced Error Reporting Capabilities: [12c] Power Budgeting <?> Kernel driver in use: lpfc
so then i need to know if the kernel driver is loaded right?
root@vmprod01 ~]# lsmod | grep lpfc lpfc 702870 0 crc_t10dif 12714 3 lpfc,target_core_mod,sd_mod scsi_transport_fc 64056 1 lpfc [root@vmprod01 ~]# modinfo lpfc filename: /lib/modules/3.10.0-327.36.3.el7.x86_64/kernel/drivers/scsi/lpfc/lpfc.ko version: 0:10.7.0.1 author: Emulex Corporation - email@example.com description: Emulex LightPulse Fibre Channel SCSI driver 10.7.0.1 license: GPL rhelversion: 7.2 srcversion: 053424650970DDDDCE74F8C - - -
OK looks like it's loadead right? What else I have to check/do to have it working? Remember I'm totally new at this.
I already try to find the solution, then asked in the CentOS forums: https://www.centos.org/forums/viewtopic.php?f=48&t=60223&p=254367#p254367
But have no luck with that.
