Emulex isn't supported by the VTL for target mode and should not be listed.

Ideally the memory sizing should be done very early and probably on a higher side than required, most of the deduplication tables can then be placed sequentially on disk. The ones created later will most lead to random IO and really can slow down the startup or shutdown time. There is an option to realign the tables sequentially but it's still work in progress. > > VTL library emulation: TS3500 (IBM 3584) > > lin_tape driver on Linux servers (with persistent device naming > configuration, as per IBM document) > Atape driver on AIX servers > > Please post the output of `lspci | grep Fibre` from the VTL server to list > all the FC cards available to the system, just to make sure. > > Best, > Sergey > > On 15 May 2020 at 17:50:27, Carlos Alexandre (carlos.xand...@gmail.com) > wrote: > > Hi, > > Qlogic does not appear but Emulex follows: > > vtl:/var/log # dmesg | grep Emulex > [ 2.633399] Emulex LightPulse Fibre Channel SCSI driver 11.4.0.7-5 > [ 2.634093] scsi host2: Emulex LPe12000 PCIe Fibre Channel Adapter on > PCI bus 06 device 00 irq 16 > [ 4.857366] scsi host10: Emulex LPe12000 PCIe Fibre Channel Adapter on > PCI bus 06 device 01 irq 17 > > > ---------------------------------------------------------------------------------------------------------------------------------------------------------------------- > vtl:/var/log # lspci -v -s 06:00.0 > 06:00.0 Fibre Channel: Emulex Corporation Saturn-X: LightPulse Fibre > Channel Host Adapter (rev 03) > Subsystem: Emulex Corporation Saturn-X: LightPulse Fibre Channel > Host Adapter > Flags: bus master, fast devsel, latency 0, IRQ 16 > Memory at fbbba000 (64-bit, non-prefetchable) [size=4K] > Memory at fbbb4000 (64-bit, non-prefetchable) [size=16K] > I/O ports at c400 [size=256] > Expansion ROM at fbb40000 [disabled] [size=256K] > Capabilities: [58] Power Management version 3 > Capabilities: [60] MSI: Enable- Count=1/16 Maskable+ 64bit+ > Capabilities: [78] MSI-X: Enable+ Count=32 Masked- > Capabilities: [84] Vital Product Data > Capabilities: [94] Express Endpoint, MSI 00 > Capabilities: [100] Advanced Error Reporting > Capabilities: [12c] Power Budgeting <?> > Kernel driver in use: lpfc > Kernel modules: lpfc > > > Regards. > > -- > You received this message because you are subscribed to the Google Groups > "QUADStor VTL" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to quadstor-vtl+unsubscr...@googlegroups.com. > To view this discussion on the web visit > https://groups.google.com/d/msgid/quadstor-vtl/da4af6d5-65a8-45c4-84bf-8e75e1598b24%40googlegroups.com > <https://groups.google.com/d/msgid/quadstor-vtl/da4af6d5-65a8-45c4-84bf-8e75e1598b24%40googlegroups.com?utm_medium=email&utm_source=footer> > . > > -- > You received this message because you are subscribed to the Google Groups > "QUADStor VTL" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to quadstor-vtl+unsubscr...@googlegroups.com. > To view this discussion on the web visit > https://groups.google.com/d/msgid/quadstor-vtl/CAAC98Q%3DkUw5E4S8A7DjULzX2OGg%3DzJ8EM4Mm8T%3DtHTPq7BSUkQ%40mail.gmail.com > <https://groups.google.com/d/msgid/quadstor-vtl/CAAC98Q%3DkUw5E4S8A7DjULzX2OGg%3DzJ8EM4Mm8T%3DtHTPq7BSUkQ%40mail.gmail.com?utm_medium=email&utm_source=footer> > . > -- You received this message because you are subscribed to the Google Groups "QUADStor VTL" group.
