更换 Veritas Access 节点
在某些情况下，您可能需要更换 Veritas Access 节点。本节介绍更换 Veritas Access 节点的步骤。
更换 Veritas Access 节点
- 从群集中删除节点之前，请确保未删除主节点。要删除主节点，您需要通过将管理控制台切换到其他节点来切换主节点。
- 如果不希望触发热重定位，请从主节点将以下可调参数设置为 -1。
#vxtune node_reloc_timeout -1
注意:
设置 node_reloc_timeout 后，storage_reloc_timeout 会自动设置为 -1。
- 对要更换的节点运行 cluster del 命令。
fss7310>cluster del fss7310_02
- 验证所有 plex 是否都处于 NODEVICE/DISABLED 状态。可以使用 #vxprint -p 命令检查 plex 状态。
- 运行以下命令，以分离卷的 plex：
# vxplex -f -g <dg-name> -o rm dis <plex-name>
- 使用 vxdg rmdisk 命令从磁盘组中删除处于
failed was:状态的所有磁盘。此命令需要从主节点运行。#vxdg –g <dg-name> rmdisk <disk-name>
- 从群集中的所有节点对删除的磁盘运行 vxdisk rm 命令。
#vxdisk rm <disk-name>
注意:
需要从群集中的所有节点对所有磁盘运行此命令。
- 在删除所有禁用的 plex 后，使用以下命令在群集中添加新节点：
fss7310>cluster add <node-ip>
- 从主节点对新添加的节点中的所有磁盘运行 storage disk format 命令。
fss7310>storage disk format <list-of-disks>
- 使用 storage pool adddisk 命令，将新添加的节点中的所有磁盘添加到创建的 Veritas Access 池中。
fss7310> storage pool adddisk pool1 <list-of-devices>
- 运行 storage fs addmirror 命令，以镜像文件系统。
fss7310> storage fs addmirror <fs-name> <pool-name>
- 此外，还要运行 vxassist 命令以镜像
_nlm_卷。#vxassist –b –g <dg-name> mirror _nlm_

更换 Veritas Access 节点
- 更改 vxtune 可调参数的值，以禁用热重定位：
# vxtune node_reloc_timeout -1
- 运行以下命令，以从群集中删除节点。
