Hello,
I have a KVM system running on RHEL 5.4. It hosts 4 guest VMs. One of the guest host fails to get back the mounted filesystems after the system reboots. Does anyone have any idea what the issue could be?

isp
ISP(4) BSD Kernel Interfaces Manual ISP(4) NAME
isp -- Qlogic based SCSI and FibreChannel SCSI Host Adapters SYNOPSIS
isp* at pci? dev? function? (PCI) isp* at sbus? slot ? offset ? (SBus) scsibus* at isp? DESCRIPTION
This driver provides access to SCSI or FibreChannel devices. SCSI features include support for Ultra SCSI and wide mode transactions for SCSI, and LVD (for the ISP1080 and ISP1280), Fibre Channel support uses FCP SCSI profile for FibreChannel. and uses Class 3 connections only. Support is available for Public and Pri- vate loops. Command tagging is supported for all (in fact, FibreChannel requires tagging). CONFIGURATION
An optional flags 0x80 appended to the above isp* declarations will disable the download of driver firmware, which means you use whatever firmware is running on the card. If no firmware is running on the card, the driver cannot operate the card. An optional flags 0x40 appended to the above isp* declarations (can be OR'd in with the other config flags option) will keep the driver from looking at device or bus NVRAM settings (this is in case NVRAM is just wrong and you have the card in a platform where it is inconvenient to change NVRAM settings on the card). HARDWARE
Supported cards include: ISP1000 SBus Fast Wide, Ultra Fast Wide cards, Single Ended or Differential cards. PTI SBS440 Performance Technology ISP1000 variants. ISP1020 Qlogic 1020 Fast Wide and Differential Fast Wide PCI cards. ISP1040 Qlogic 1040 Ultra Wide and Differential Ultra Wide PCI cards. PTI SBS450 Performance Technology ISP1040 variants.

The isp driver was written by Matthew Jacob for NASA/Ames Research Center. BUGS
The driver currently ignores some NVRAM settings. The driver currently doesn't do error recovery for timed out commands very gracefully. Sometimes, when booting, the driver gets stuck waiting for the Fibre Channel firmware to tell it that the loop port database is ready. In this case you'll see an announcement that the loop state has a value of 0x1. To unwedge the system, unplug and replug the fibre channel con- nection, or otherwise cause a LIP (Loop Initialization Primitive sequence) - this will kick the firmware into getting unstuck. BSD
