Has anyone seen an issue where an iSCSI target device is visible to lsscsi but no device directory is allocated in /sys/devices/platform?
The server is an IBM Xserve 3650 with 8 local SAS drives (3 logical units), with 8 Ethernet NICs, 3 connected. The two onboard Broadcom NICs are connected to the local server vlan and an iSCSI switch respectively; the third is a intel PCI-X multiport board with 1 iSCSI link to a different iSCSI switch. VLAN MTU/MRU is 1500 bytes, iSCSI is 9000. The OS is redhat 5.6, fully patched. The iSCSI array is a Dell md3200i. The iSCSI switches are Dell. What's driving us batty is that another similar server connected to a different Dell md3200i array is fine. A couple of day of groveling in the Redhat, Dell, and general internet iscsi stuff hasn't turned up either this problem or a likely solution. The working and non-working systems are using the same Dell switches, which have only iSCSI traffic. Unplugging either of the iSCSI Ethernet cables makes no difference. Booting older kernels makes no difference. . iscsiadm is successfully logging into the array. lsscsi is showing and /sys is allocating and udev is creating block devices for the generic Dell 20 MB drive target. But the specifically allocated drive is only half-visible: lsscsi sees it, sysfs and udev do not. -- Jim Leinweber State Laboratory of Hygiene, University of Wisconsin - Madison <[email protected]> 2810 Walton Commons West; phone +1 608 221 6281 PGP fp: D573 AF7D F484 EE2A F0B6 B7DB A870 7518 F87D A0D1 _______________________________________________ rhelv5-list mailing list [email protected] https://www.redhat.com/mailman/listinfo/rhelv5-list
