Probably depends on the back end device and the driver, if they are not both IBM then you need to check the vendor specific procedure to see it they support this.

Posting the exact error instead of "I'm getting an error that none of the volumes have increased in size." may also help us to help you...

oslevel and hacmp info wouldn't hurt either...

Solaris10 -> iscsi -> equiliogic lun

We "lose" the iscsi device after a reboot - i.e., it appears in /dev/rdsk and /dev/dsk but format cannot find it. Obviously, it won't mount either. This happens for two separately defined luns. We must be missing a step in iscsiadm. The luns are defined as targets, we can see them in... (2 Replies)

MFI(4)							   BSD Kernel Interfaces Manual 						    MFI(4)

NAME
mfi -- LSI MegaRAID SAS driver SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file: device pci device mfi Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): mfi_load="YES" DESCRIPTION
This driver is for LSI's next generation PCI Express SAS RAID controllers. Access to RAID arrays (logical disks) from this driver is pro- vided via /dev/mfid? device nodes. A simple management interface is also provided on a per-controller basis via the /dev/mfi? device node. The mfi name is derived from the phrase "MegaRAID Firmware Interface", which is substantially different than the old "MegaRAID" interface and thus requires a new driver. Older SCSI and SATA MegaRAID cards are supported by amr(4) and will not work with this driver. Two sysctls are provided to tune the mfi driver's behavior when a request is made to remove a mounted volume. By default the driver will disallow any requests to remove a mounted volume. If the sysctl dev.mfi.%d.delete_busy_volumes is set to 1, then the driver will allow mounted volumes to be removed. A tunable is provided to adjust the mfi driver's behaviour when attaching to a card. By default the driver will attach to all known cards with high probe priority. If the tunable hw.mfi.mrsas_enable is set to 1, then the driver will reduce its probe priority to allow mrsas to attach to the card instead of mfi. HARDWARE
The mfi driver supports the following hardware: o LSI MegaRAID SAS 1078 o LSI MegaRAID SAS 8408E o LSI MegaRAID SAS 8480E o LSI MegaRAID SAS 9240 o LSI MegaRAID SAS 9260 o Dell PERC5 o Dell PERC6 o IBM ServeRAID M1015 SAS/SATA o IBM ServeRAID M1115 SAS/SATA o IBM ServeRAID M5015 SAS/SATA o IBM ServeRAID M5110 SAS/SATA o IBM ServeRAID-MR10i o Intel RAID Controller SRCSAS18E o Intel RAID Controller SROMBSAS18E FILES
