Hi,
I am trying to configure ASMLib with RHEL 4.0 update 2 with multipath
devices.
I have 2 DELL Itanium 2 servers.
Each server has 2 QLogic cards. I configured multipath driver. This driver
created for me 3 devices in /dev/mapper:
[root at hacksaw mapper]# ls -l
total 0
brw-rw---- 1 root disk 253, 0 Oct 21 13:53
360a9800056716a37473430716c465849
brw-rw---- 1 root disk 253, 1 Oct 21 13:53
360a9800056716a37473430716c4b7065
brw-rw---- 1 root disk 253, 2 Oct 21 13:53
360a9800056716a37473430716c4d4a46
Those devices represented disks:
[root at hacksaw mapper]# multipath -l
360a9800056716a37473430716c4b7065
[size=110 GB][features="0"][hwhandler="0"]
\_ round-robin 0 [active]
\_ 3:0:0:9 sdc 8:32 [active]
\_ 3:0:3:9 sdf 8:80 [active]
\_ 4:0:0:9 sdi 8:128 [active]
\_ 4:0:3:9 sdl 8:176 [active]
360a9800056716a37473430716c465849
[size=35 GB][features="0"][hwhandler="0"]
\_ round-robin 0 [active]

\_ 3:0:3:8 sde 8:64 [active]
\_ 4:0:0:8 sdh 8:112 [active]
\_ 4:0:3:8 sdk 8:160 [active]
360a9800056716a37473430716c4d4a46
[size=124 GB][features="0"][hwhandler="0"]
\_ round-robin 0 [active]
\_ 3:0:0:10 sdd 8:48 [active]
\_ 3:0:3:10 sdg 8:96 [active]
\_ 4:0:0:10 sdj 8:144 [active]
\_ 4:0:3:10 sdm 8:192 [active]
After that I created partitions for thise devices:
[root at hacksaw mapper]# kpartx -l
/dev/mapper/360a9800056716a37473430716c465849
360a9800056716a37473430716c465849p1 : 0 489440
/dev/mapper/360a9800056716a37473430716c465849 32
360a9800056716a37473430716c465849p2 : 0 149504
/dev/mapper/360a9800056716a37473430716c465849 489472
360a9800056716a37473430716c465849p3 : 0 72769536
/dev/mapper/360a9800056716a37473430716c465849 638976
I can see them from fdisk /dev/mapper/360a9800056716a37473430716c465849
When I am executing
[root at hacksaw mapper]# asmtool -l /dev/oracleasm -C -n REP1 -s
/dev/mapper/360a9800056716a37473430716c465849p3
asmtool: Device "/dev/mapper/360a9800056716a37473430716c465849p3" is not a
partition
I have created trace file :
strace -f -o /tmp/log asmtool -l /dev/oracleasm -C -n REP1 -s
/dev/mapper/360a9800056716a37473430716c465849p
It generates me errors:
7345 ioctl(4, 0x4c05, 0x60000fffffffb230) = -1 ENOTTY (Inappropriate ioctl
for device)
7345 ioctl(4, 0x4c03, 0x60000fffffffb230) = -1 ENOTTY (Inappropriate ioctl
for device)
7345 ioctl(4, 0x301, 0x60000fffffffb620) = -1 ENOTTY (Inappropriate ioctl
for device)
Am I using wron partition names?
Thanks,
Sergey Rodionov
