Hello
Our customer asked me delay time on using srp protocol.
They were using SRP Protocol for Storage.
This server did not occur delay time(linux start) before changed OS Version.
The server display the volume using srp instantly When this server booting.
but they changed Version some of them OS.
All of them occurred delay time on booting.
HCA Card
- Single Port HCA : MHQH19B-XTR (fw ver. : 2.9.1000)
- Dual Port HCA : MHQH29C-XTR (fw ver. : 2.9.1000)
One server
OS : CentOS 5,7 (x86_64)
OFED : MLNX_OFED_LINUX-1.5.3-1.0.0.2-rhel5.7-x86_64.iso
è The one server connected the DDN Storage directly.
This server did not occur delay time.
Four server
OS : CentOS 6.3 (x86_64)
OFED : MLNX_OFED_LINUX-1.5.3-3.1.0-rhel6.3-x86_64.iso
è The 4 servers connected the DDN Storage through the IB Switch
They tested the below.
1. 1. /usr/sbin/srp_daemon.sh retry value change 60s --> 30s
è Samething(delay time)
2. 2. HCA Card changed the latest version (2.9.1000 --> 2.11.500)
è Samething(delay time)
3. 3. Setting "/etc/ddn/srp_daemon.conf"
a id_ext=c0cd100003c90200,ioc_guid=0002c9030010cd18
a id_ext=c0d5070003c90200,ioc_guid=0002c9030007d554
4. 4. Setting “/etc/infiniband/openib.conf”
