From 9eafa1de73d1bd0b2ac0275d1389824825647df7 Mon Sep 17 00:00:00 2001 From: Maciej Naruszewicz Date: Thu, 4 Oct 2012 16:34:11 +1000 Subject: imsm: Allow to specify controller for --detail-platform. Usually, 'mdadm --detail-platform -e imsm' scans all the controllers looking for IMSM capabilities. This patch provides the possibility to specify a controller to scan, enabling custom usage by other processes - especially with the --export switch. $ mdadm --detail-platform Platform : Intel(R) Matrix Storage Manager Version : 9.5.0.1037 RAID Levels : raid0 raid1 raid10 raid5 Chunk Sizes : 4k 8k 16k 32k 64k 128k 2TB volumes : supported 2TB disks : not supported Max Disks : 7 Max Volumes : 2 per array, 4 per controller I/O Controller : /sys/devices/pci0000:00/0000:00:1f.2 (SATA) $ mdadm --detail-platform /sys/devices/pci0000:00/0000:00:1f.2 Platform : Intel(R) Matrix Storage Manager Version : 9.5.0.1037 RAID Levels : raid0 raid1 raid10 raid5 Chunk Sizes : 4k 8k 16k 32k 64k 128k 2TB volumes : supported 2TB disks : not supported Max Disks : 7 Max Volumes : 2 per array, 4 per controller I/O Controller : /sys/devices/pci0000:00/0000:00:1f.2 (SATA) $ mdadm --detail-platform /sys/devices/pci0000:00/0000:00:1f.2 --export MD_FIRMWARE_TYPE=imsm IMSM_VERSION=9.5.0.1037 IMSM_SUPPORTED_RAID_LEVELS=raid0 raid1 raid10 raid5 IMSM_SUPPORTED_CHUNK_SIZES=4k 8k 16k 32k 64k 128k IMSM_2TB_VOLUMES=yes IMSM_2TB_DISKS=no IMSM_MAX_DISKS=7 IMSM_MAX_VOLUMES_PER_ARRAY=2 IMSM_MAX_VOLUMES_PER_CONTROLLER=4 $ mdadm --detail-platform /sys/devices/pci0000:00/0000:00:1f.0 # This isn't an IMSM-capable controller mdadm: no active Intel(R) RAID controller found under /sys/devices/pci0000:00/0000:00:1f.0 Signed-off-by: Maciej Naruszewicz Signed-off-by: NeilBrown --- Create.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'Create.c') diff --git a/Create.c b/Create.c index 32683a82..2da07d06 100644 --- a/Create.c +++ b/Create.c @@ -492,7 +492,7 @@ int Create(struct supertype *st, char *mddev, warn = 1; } - if (st->ss->detail_platform && st->ss->detail_platform(0, 1) != 0) { + if (st->ss->detail_platform && st->ss->detail_platform(0, 1, NULL) != 0) { if (c->runstop != 1 || c->verbose >= 0) pr_err("%s unable to enumerate platform support\n" " array may not be compatible with hardware/firmware\n", -- cgit v1.2.3
